ETHERNET GROWING IN CHINA

December 5, 2013 - The Chinese market for industrial Ethernet & Fieldbus Technologies grew by 18 million nodes in 2012. More than 3 million nodes used Ethernet and the remainder used Fieldbus technology.

Although Fieldbus has a large base of new connected nodes in China, the usage of Fieldbus is not as common as in developed countries such as Germany or the United States. This is mainly because Chinese customers are encountering networking technology much later than those developing countries.

However, the growing speed of Ethernet is quite considerable in China and we think it is a great opportunity for Chinese customers to upgrade their automation system under current market condition. Customers will just jump from old Fieldbus Technologies direct to Ethernet now and actually many of them are doing right now.  The Chinese market is currently engaged in extensive upgrading and new infrastructure construction, and that will require a great deal of Ethernet applications.

CAN AUTOMATION VENDORS SERVE TWO MASTERS?

Service Dynamics
The primary objective of a service company should be to focus on the development a system solution that is uniquely suited to the idiosyncrasies of the client’s business without being tethered by particular product solution offerings. A big part of this is the ability to deploy technologies from appropriate sources using integration and engineering skills to achieve a superior result for the client. Service businesses need to have effective and refined project, personnel, and quality management systems. The growth and effectiveness of these businesses is directly related to adding and managing smart people and this is a unique business proficiency mastered by successful service organizations. Pure service businesses have an advantage of successfully maintaining alliances with a range of product vendors that cannot be logically achieved by product vendors who provide services. This separation positions a pure service business to use best of breed and get the most out of vendors. For comparison, consider you are a smartphone user and the only place to get apps was your phone hardware vendor.
Inherent Conflict

The dynamics of a service business and innovative product business are dramatically different. Established product companies tend to emphasize the practices and culture they know best when they move into services. The tendency is to find synergies based on their products that become the recommended solutions for customers. Additionally, it can be more difficult for a product company who provides services to be the champion for the customer when there is a problem with the product being implemented.
Ideal Product Company Focus

I believe that product companies should always be striving to eliminate implementation and operations labor with improved and innovative automation technology. There is an inherent conflict by having a company that provides services and products.

Industrial automation systems are performing more tasks and doing so more quickly

industrial automation systems are performing more tasks and doing so more quickly, more accurately, and in harsher environments than ever before. They are becoming connected tools with substantially more computing and communication capabilities, allowing them to interoperate with other devices. As they evolve and proliferate, these systems put new demands on their computing technology. Rugged COM Express modules not only meet the computing needs of today’s rapidly changing industrial landscape, but also protect the investment to meet tomorrow’s performance needs.

At the dawn of the “Industrial Internet,” the ante is being upped for modular embedded systems. More and more machines are being connected, many in remote and challenging environments such as oil and gas, locomotives, transportation, and ship-propulsion systems. To meet the demand for more data in less time, these systems must work faster and longer. Accelerating with the demand for data is the evolution of computer processors. But businesses can’t afford the downtime required to replace processors, or the expense of replacing the carrier board when upgrading the processor. According to a 2006 Department of Energy study, idle industrial machinery can cost as much as $800 per minute.


What’s needed is a modular embedded computing architecture that addresses these cost and downtime issues. Perhaps the most compelling of the modular architectures available today is COM Express. COM Express provides the requisite computing power for today’s increasingly connected world while also extending the lifespan of the underlying system. As chip technology evolves, users can switch out the module without adverse effect on the underlying hardware and assets – saving time and money. The modularity, simplicity, and reliability of COM Express technology help businesses remain competitive, profitable, and flexible.

Transitioning to DO-178C and ARP4754A for UAV software development using model design

With the FAA and EASA adopting aviation standards such as DO-178C and ARP4754A, UAV software developers should familiarize themselves with these standards, particularly when transitioning to model-based design.
Few applications place more importance on verification, or prescribe more process guidance, than aviation. The FAA and its European equivalent, EASA, provide guidance using standards such as ARP4754 for aircraft systems and DO-178B for flight software. These standards are often used outside of civil aviation, in whole or in part, for applications including military aircraft and land vehicles. Adoption for UAV programs is rapidly growing because of the FAA’s recent decision to require UAS and OPA certification via FAA Order 8130.34A. UAV systems are heterogeneous, and not restricted just to flight software. Therefore, other standards are used such as DO-254 for hardware and DO-278 for ground and space software.
With model-based design, UAV engineers develop and simulate system models comprised of hardware and software using block diagrams and state charts, as shown in Figures 1 and 2. They then automatically generate, deploy, and verify code on their embedded systems. With textual computation languages and block diagram model tools, one can generate code in C, C++, Verilog, and VHDL languages, enabling implementation on MCU, DSP[], FPGA[], and ASIC hardware. This lets system, software, and hardware engineers collaborate using the same tools and environment to develop, implement, and verify systems. Given their auto-nomous nature, UAV systems heavily employ closed-loop controls, making system modeling and closed-loop simulation, as shown in Figures 1 and 2, a natural fit.
ARP4754A addresses the complete aircraft development cycle from requirements to integration through verification for three levels of abstraction: aircraft, systems, and item. An item is defined as a hardware or software element having bounded and well defined interfaces. According to the standard, aircraft requirements are allocated to system requirements, which are then allocated to item requirements.
The fact that ARP4754A addresses allocation of system requirements to hardware and software components is significant to UAV developers, especially suppliers. Some suppliers might have claimed that UAV subsystem development was beyond the scope of the original ARP4754, even for complex subsystems containing hardware and software, but not anymore. ARP4754A also more clearly refers to DO-178 and DO-254 for item design. In fact, the introductory notes for ARP4754A acknowledge that its working groups coordinated with RTCA special committees to ensure that the terminology and approach being used are consistent with those being developed for the DO-178B update [DO-178C].
Given the high coupling among systems, hardware, and software for UAVs, it is helpful that the governing standards now clarify relationships between systems and hardware/software subsystems.
ARP4754A recommends the use of modeling and simulation for several process-integral activities involving requirements capture and requirements validation.
ARP4754A Table 6 recommends (R) analysis, modeling and simulation (tests) for validating requirements at the highest Development Assurance Levels (A and B). For Level C, modeling is listed as one of several recommendations. While ARP4754 made similar recommendations, ARP4754A provides more insight and states that a representative environment model, such as the plant model shown in Figure 1, is an essential part of a system model.
Also noted in ARP4754A is that a graphical representation or model can be used to capture system requirements. The standard now notes that a model can be reused for software and hardware design.
If engineers use models to capture requirements, ARP4754A recommends engineers consider the following:
1. Identify the use of models/modeling
2. Identify the intended tools and their usage during development
3. Define modeling standards and libraries
When using model-based design with ARP4754A and DO-178C, additional verification capabilities are often needed beyond in-the-loop testing described in Table 2. These including requirement tracing, model standard checking, model-to-code structural equivalence checking, and robustness analysis using formal methods. For UAVs, rigorous verification that includes multiple verification technologies is paramount given their autonomous nature and system complexity.
DO-178C
Not surprisingly, one of the first changes new in DO-178C is an explicit mention of ARP4754A in Section 2: System life-cycle processes can be found in other industry documents (for example, SAE ARP4754A).
Clarification updates aside, such as the one noted earlier, DO-178C does not differ significantly from DO-178B, at least at first glance. In fact, a casual reader might miss an item mentioned in Section 1.4: How to Use this Document: One or more supplements to this document exist and extend the guidance in this document to a specific technique… if a supplement exists for a specific technique, the supplement should be used …
In other words, the standard’s big changes are captured in the supplemental documents, such as RTCA DO-331, Model-Based Development and Verification Supplement to DO-178C and DO-278A.
Pertinent to this discussion, a long-standing issue with DO-178B for practitioners of model-based design is the uncertainty in mapping DO-178B objectives to model-based design artifacts. Addressing this mapping was a main goal of the DO-178C Sub-Group (SG-4) focused on model-based design. No single mapping sufficed, so several mappings are provided in DO-331. Some include the concept of a Specification model, which is a model separate from that of the one used for design and code generation. The other concept is a Design model, which serves as the detailed requirements used to generate code.

Asia claims almost half of Industrial automation system solutions


In order to help businesses better understand how to take advantage of the current climate and increase their industrial automation sales in Asia, particularly China, the CC-Link Partner Association (CLPA) is hosting a seminar entitled ‘Gateway to China’. The event will take place on 24th September at the Mitsubishi Electric Europe Tokyo Conference Suite in Hatfield.
In light of the sensitive current economic climate, many Asian companies are taking a more careful approach to investment – they are becoming more demanding towards their suppliers and making more enquiries before purchasing. Furthermore, according to IHS’ research, several Chinese manufacturers are currently developing products which are in direct competition with the ones provided by Western suppliers of industrial automation. These are only a few of the obstacles facing European vendors who want to penetrate the Asian market to change the way they do business.

Flexibility and the ability to respond to very specific demands are becoming essential factors when dealing with the Asian market. Being able to offer technologies and solutions which are compatible with the needs of Asian clients is no longer an option, it’s a must.

Salary increase comparison



Another expected data point is that the average salary of an employee gradually increases with the number of people reporting to him or her. With no direct reports, the average salary is $102,170. The average salary increases to more than $200,000 when the number of reports exceeds 500 people.

If you look around your office or attend any embedded computer events, you will notice the sheer lack of females in the automation profession. This year the percentage of female respondents crept up slightly from 5.1% last year to 6.3%. Along with that gender gap comes a salary gap of about $11,283. The average salary for a male is $107,487, while the average salary for a female is $96,204.

Does company size matter?Are you thinking of becoming an independent contractor? Our survey indicates that contractors make about $10,000 more per year than a direct employee. The average salary of a contractor (5.3% of respondents) is $116,636. That $10K may not be enough to cover the cost of insurance and other benefits available to direct employees, however.

There is a message here for employers. If you are paying less than the industry average, you could very likely lose your engineers. Based on data from industrial auto machines, a recruiting and contract staffing company based in Minnesota, there is a high demand for automation professionals, and high-quality candidates are hard to find. When companies do find good candidates, the candidates typically have multiple offers on the table. If your company employs high-quality professionals, pay them well, or you may lose them.

Tips 101: Safety options for automotive chips


Redundant critical on-chip modules like processor, ISO, DMA controller, internal clock generator, and communications peripherals can improve reliability should a primary hardware module become non-functional while the vehicle is running. Such a system can have in-built error detection mechanisms and on-the-fly switching to redundant hardware to mitigate threats to passenger safety.
But this kind of redundant hardware architecture comes with the penalty of increased area and higher power management in silicon. Area penalties can be minimized by intelligent selection of which functions need to be duplicated in silicon. Power can be minimized by adopting power and clock gating in the redundant modules. Some  in-vehicle computers can be implemented in lock-step of each other, where primary and redundant modules process the same input. Mismatch in the output of the lock-step modules indicates a defect in either of the modules. The system can switch itself off or take appropriate safety measures to avoid any real-time failure. Redundant hardware should be placed quite far in silicon from the primary embedded systems to avoid tampering of both modules together.

IT Technology for industrial controls

It is the author’s opinion that integration of the controls networking  and the IT network is inevitable. It became inevitable the moment the controls industry chose to use Ethernet as the medium with which to communicate data. The controls industry may choose to be dragged kicking and screaming into the modern automation  era, or it can gracefully embrace the change. Embracing means the controls industry would be able to leverage the myriad rich, existing technologies that have been proven foolproof in the IT world. To be dragged kicking and screaming into the modern communications era would do a terrible injustice to those who have worked diligently to bring it about. This could quite possibly add an entirely new facet to the fieldbus wars, which I hope have not been forgotten.
With that said, the controls world is going to be moving with an industry that has a definite consumer bias, with product development and release cycles of six months or less. In an industry where the average life expectancy of an automotive production line is eight years, it is impossible to expect the networking in an industrial setting to keep up with modern IT standards. Therefore, we turn our attention to the technologies that have existed the longest, with the most open standards and the very best support. These are the protocols we wish to use and keep, and this article highlights and explains some of these technologies.

Security and reliability is an utter-most issue


A factory is only as strong as its weakest link, so every Internet of Things client in the factory needs protection from viruses, malware, and hacking to prevent costly interruptions to factory operation. The 4th generation Intel Core processor adds a number of features to its security portfolio, including McAfee’s Deep Defender technology, which resides between the memory and embedded system to perform real-time memory and CPU monitoring without impacting overall system performance. (McAfee is an Associate member of the Alliance.) As shown in Figure 5 (page 22), additional security elements include multiple solutions. TenAsys also offers the INtime RTOS family, which can run as a stand-alone RTOS or alongside Microsoft Windows as shown in Figure 3. Both products enable users to partition a multicore platform to run mixed fanless embedded systems, making better use of the processor’s advanced features to provide highly integrated  solutions. (Microsoft and TenAsys are both Associate members of the Alliance.)

Power plant efficiency in search


In power plant, the actuator and valve create a single unit — the control valve. Actuators perform different motion sequences, including linear, pivoting and rotating motions, and they are powered by pneumatic, hydraulic or electrical energy. Actuators receive a control signal from automation systems and single board computer. The single board computer is converted into a motion so that the control element of the actuating element assumes a corresponding position. With control valves, this is a stroke motion. With flaps, ball cocks or rotary plug valves, this is a pivoting motion.
Power plants have traditionally used pneumatic actuators to drive the many control valves throughout their facilities. However, major improvements in embedded systems control-valve actuator technology are helping power providers achieve their most important objectives at a lower cost.
The new electric actuators can hold up to the demands of continuous movement.

Satisfying rugged memory requirements


While demands for ruggedized embedded devices continue to rise, memory module suppliers continue to make technology advancements and associated manufacturing enhancements that meet the needs of OEMs. DDR3 SODIMM, DDR3L, and lower-profile DDR3L are all examples of new technologies that help satisfy rugged memory requirements. These advancements solve many design challenges, including low power, enhanced thermal dissipation, and extended-temperature tolerance while delivering the performance needed for today’s complex embedded systems.

Embedded developers challenge to fasten system operating

Developers can often find answers to their questions through the Internet, but no one is on the hook to research and respond to a embedded computer specific question. Open source products are generalized in order to fit the widest array of users and can force designers to modify the hardware configuration, resulting in higher recurring cost for the embedded device. Cost is obviously a major deciding factor when selecting an embedded operating system. Since there is essentially no cost of goods with software, vendors can adjust their pricing model to generate revenue from various sources. Vendors can charge for an initial license fee, development seats per engineer, development tools, per-unit royalties, continuing support, or major upgrades. To fairly compare prices, the overall cost of ownership must be computed for each OS being considered.
 

Memory needs for in-vehicle system

Automotive electronics are memory hungry. Therefore, the explosive growth of in-vehicle infotainment systems in modern cars has a significant impact on the market demand for semiconductor memories. For 2012, the average memory content of a car was estimated to be around US$12.8, ranging from US$2.0 for low-end models to more than US$100 for fully equipped luxury vehicles. As a result, the total available market value for in-vehicle memories in automotive applications is expected to reach a Compounded Annual Growth Rate (CAGR) of more than 9 percent from 2011 to 2015, well above the overall CAGR for the total memory semiconductor market, which is less than 7 percent.

“Many people initially think a cloud is inherently insecure as it is a single point of failure –the cloud goes and all your data goes with it,” says Todd Moore, Vice President of Product Management at SafeNet (www.safenet.com). “However, embedded computer build in redundancy so when they write data to a cloud, they also write it to a disk at the same time. The virtual environment is encrypted and is also stored on a disk.”
“Securing the cloud is simple, as it is about providing assurance,” says Will Keegan, Technical Director, Software Security at LynuxWorks (www.lynuxworks.com). “Users need to feel comfortable that when they log on remotely, every transaction they make will be secure. The complexities of public ISP embedded computer systems are too high to assure that data loss or leakages cannot occur. In a public cloud you have to assume all users are adversaries, and we rely on the ISP to protect other customers from stealing my data.”

Embedded product development and networking



Testing and traceability play a vital role in embedded product development. Traceability rendered via Application Life-cycle Management (ALM) software enables the team to automatically generate networking cases that link back to requirements, and report defects that link back to test cases. By knowing that defects are addressed and test cases run successfully, the team can have an immediate networking and accurate accounting of the state of product requirements.

Fifteen or 20 years ago, many embedded systems consisted of an 8-bit processor with a few KB of memory and perhaps a couple hundred lines of networking. Today, the explosion of embedded systems in automobiles, ATMs, cell phones, and other devices has dramatically changed that dynamic. It’s not uncommon to see multiple 32- and 64-bit multicore processors on an Ethernet network, running multiple applications totaling hundreds of thousands of lines of code in these systems.

About building, maintaining, and evolving proprietary network systems

Industrial computer, Panel PC, networking appliance

In recent years, building, maintaining, and evolving proprietary network systems for telecom-grade applications that are highly available and "always on" have become increasingly prohibitive from the perspective of cost, risk management, time to revenue, and so on. The custom-built approach becomes even less cost effective as Communications Service Providers (CSPs) move toward offering cloud-based services, where they have to compete with non-traditional providers that offer such services on networks built using Commercial Off-The-Shelf (COTS) building blocks.

A change in market dynamics is causing a fundamental paradigm shift in industry's thinking: Instead of continuing to invest precious Research and Development (R&D) resources and dollars to build expensive, special-purpose proprietary systems with the hope that they will never fail, industry leaders are now assuming that there will be hardware and software failures and thus designing systems and applications that continue to provide end-user service in the presence of such failures.
State-of-the-art software and related standards have made significant advances in recent years to support sophisticated schemes and quick implementation of highly available applications and services that can run on relatively inexpensive COTS hardware systems. Some significant industry standardization efforts are:
  • PCI Industrial Computer Manufacturers Group (PICMG), an industry consortium that creates and promotes COTS hardware standards that can be used for a variety of network applications
  • The Carrier Grade Linux effort of the Linux Foundation that has helped create a version of Linux suitable for telecom gear
  • The Service Availability Forum (SAF), whose interface specifications have long been used to develop COTS middleware that ensures uninterrupted service availability of network applications. Multiple implementations of these specifications exist, including an open source version that is available from the OpenSAF

New challenge for gaming industry


Industrial computer, Panel PC, networking appliance
Ecosystems for tremendous gaming platforms factors exist at various levels, making some more popular than others. Companies still continue to develop proprietary mezzanines to meet specific requirements, and this is expected to continue as long as gaming platforms components exist.
Gaming platform are an important design element to many board form factors. They grew out of a necessity to gain more board real estate or to incorporate modular flexibility to the original form factor. In the early days, few, if any, standards for mezzanines existed. However, over time, standards emerged to make it easier to incorporate mezzanines into designs

Top 10 Chopper with embedded technology

Embedded computers, gaming platform, Console server
The embedded medical department of Ludwig Maximilian University of Munich (LMU), Germany, is cooperating with the Health Foundation Hospital in Noerdlingen in testing the exchange of real-time medical images and other medical data during an operation or other emergency tasks. LMU not only educates medical students, but also operates one of the most embedded  hospitals in Germany. The hospital in Noerdlingen is small and old, founded in the 13th century, but very modern. It serves several small communities around it.
Noerdlingen is fairly remote by German standards, which is one reason why it was chosen for this embedded application. So if an operation is or becomes critical, experts in Munich can literally see what is going on in the operation room in Noerdlingen and give recommendations on what to do or analyze the available data, including Computed Tomography (CT) scans. A number of embedded electronic devices (blood pressure, heart frequency, ultrasound, laser imaging, nerve reaction speed, and so on), high-performance computer systems, and high-speed communications links are involved in this application.

Deploying techniques on industrial-computer-boards

Requirements to deploy
Most of the requirements to deploy a critical system are based on the real-time response of the system to the processes they monitor and control. The top requirements are related to:
  • Memory protection - A misbehaved thread can corrupt the kernel's own code or internal data structures causing all types of bad behaviors to the system.
  • Fault tolerance and high availability - Even the best software has latent bugs. As applications become more complex and perform more functions, the number of bugs in fielded systems continues to rise. System designers must, therefore, plan for failures and employ fault recovery techniques.
  • Mandatory vs. discretionary access control - Mandatory access control provides guarantees to the access of a device or file. Discretionary access controls are only as effective as the applications using them, and these applications must be assumed to have bugs in them.
  • Guaranteed resource availability: space domain and time domain - A critical process cannot, as a result of malicious or careless execution of another process, run out of memory resources or deadlock due to priority conflicts that block resources.
  • Schedulability - Meeting hard deadlines is especially important, and missing a deadline can be a critical fault; the access to system services must be deterministic.
  • Interrupt latency - Some interrupts are higher priority and require a faster response time than others; how long it takes to respond is critical.
  • Bounded execution times - Just as response time is critical, how long a task takes to execute is also important.
  • Priority inversion - A lower task can block a higher priority task; predictably resolving the block is a must.
  • Security - Everything is becoming connected, so trusted computing is more important than ever to prevent malicious attacks.

Growing pressure to boost the performance

Embedded PC, in vehicle PC, Industrial PC
In response to growing pressure to boost the performance and trim down the size of embedded applications, standards organizations meet regularly to optimize their portfolios in light of the latest available technology. These updated standards take advantage of new silicon architecture combining multiple processors, graphics elements, and complex I/O to deliver the next generation of preengineered, off-the-shelf modules to support many of the high-performance requirements of embedded product development.
These standardized computer platforms allow designers to trade in substantial savings in Non-Recurring Engineering (NRE) and scheduling for slightly higher recurring costs. Standards-based designs also shortcut the software development effort by providing access to compatible operating systems, vendor-supplied drivers, and sample firmware.
In the Strategies section of this issue, we asked experts from several standards organizations to bring us up to date on the latest changes affecting embedded designs. Starting things off, Jim Blazer, CTO at RTD Embedded Technologies and active member of the PC/104 Consortium, presents the history and updates in work – such as the latest generation of PCI Express – that support the PC/104 stackable architecture. Citing the need for smaller and more rugged building blocks, Alexander Lockinger, President of the Small Form Factor Special Interest Group (SFF-SIG) and CTO at Ascend Electronics, covers the trends and new products to expect in 2013. In addition, Jerry Gipper, Director of Marketing at VITA and Editorial Director ofVITA Technologies magazine, reports on the recent Embedded Tech Trends 2013 meeting aboard the Queen Mary and standards work in progress, plus some new technologies such as optical interconnects.

Under increasing pressure ....

 IT managers are under increasing pressure to boost network capacity and performance to cope with the data deluge. Networking systems are under a similar form of stress with their performance degrading as new capabilities are added in software. The solution to both needs is next-generation System-on-Chip (SoC) communications processors that combine multiple cores with multiple hardware acceleration engines.

 

The data deluge, with its massive growth in both mobile and enterprise network traffic, is driving substantial changes in the architectures of base stations, routers, gateways, and other networking systems. To maintain high performance as traffic volume and velocity continue to grow, next-generation communications processors combine multicore processors with specialized hardware acceleration engines in SoC ICs.
The following discussion examines the role of the SoC in today’s network infrastructures, as well as how the SoC will evolve in coming years. Before doing so, it is instructive to consider some of the trends driving this need.

About performance management issue

Embedded computers, gaming platform, Console server
 

Given the increased complexity of processors and applications, the current generation of Operating Systems (OSs) focuses mostly on software integrity while partially neglecting the need to extract maximum performance out of the existing hardware.

Processors perform as well as OSs allow them to. A computing platform,  or otherwise, consists of not only physical resources – memory, CPU cores, peripherals, and buses – managed with some success by resource partitioning (virtualization), but also performance resources such as CPU cycles, clock speed, memory and I/O bandwidth, and main/cache memory space. These resources are managed by ancient methods like priority or time slices or not managed at all. As a result, processors are underutilized and consume too much energy, robbing them of their true performance potential.
Most existing management schemes are fragmented. CPU cycles are managed by priorities and temporal isolation, meaning applications that need to finish in a preset amount of time are reserved that time, whether they actually need it or not. Because execution time is not safely predictable due to cache misses, miss speculation, and I/O blocking, the reserved time is typically longer than it needs to be. To ensure that the modem stack in a smartphone receives enough CPU cycles to carry on a call, other applications might be restricted to not run concurrently. This explains why some users of an unnamed brand handset complain that when the phone rings, GPS drops.

Development of M2M devices

With advances in wireless technologies, defining a strategy for building wireless M2M-enabled devices is not the dauntingly complex task it was once thought to be. Instead of devoting precious R&D resources to the integration of fragmented, ad hoc technologies, today’s developers can take advantage of increasingly sophisticated Embedded Application Frameworks (Linux, Android, and others), some of which are highly optimized for M2M application development.

Industrial computer, Panel PC, networking appliance
 
Machine-to-Machine (M2M) communication, or the ability to connect and manage remote devices over the air, offers enormous potential. With the ability to centrally control remote industrial equipment, trackvehicle fleets, manage electric vehicle charging stations, expand the capabilities of consumer devices, and much more, M2M has profound implications for virtually every industry.
Given the novelty of M2M technology, however, developing connected devices has traditionally been an expensive and time-consuming process, largely due to the fact that system designers had to build the entire M2M architecture from scratch. Today, designers have a powerful new option in their M2M toolkit: Embedded Application Frameworks (EAFs). By deploying connected services on mature, prepackaged Real-Time Operating Systems (RTOSs) and libraries embedded directly into the communications module, M2M designers can substantially reduce the time and costs involved in developing new M2M hardware and focus their efforts on creating innovative connected applications.

Industry: Innovation driven by electronics

Industrial computer, Panel PC, networking appliance
 

High-end electronics provide drivers and passengers with in-car navigation and entertainment and information delivered over a wireless network. In fact, many car buyers today care more about the infotainment technologies embedded in the dashboard than what's under the hood. This phenomenon is requiring additional storage space for rich multimedia data and advanced software and applications and is driving an explosive growth of both volatile and nonvolatile memories. Embedded multimedia cards are helping meet this demand in today's memory-hungry automotives.

The automotive market is moderately but steadily growing. Global car sales rose 6 percent year-on-year in the first half of 2012, despite the ongoing headwinds associated with the sovereign debt problems in Western Europe and some moderation in the pace of global economic activity. Global sales of passenger  and light commercial vehicles are expected to grow from 78 million units in 2011 to more than 100 million units in 2018. In a recent study, Gartner confirmed that electronics are playing a major role in the advancement of automotive technology. Electronic content in cars has been steadily increasing since the first digital engine control modules were introduced in the ’80s.
Today, microelectronics enable advanced safety features, new information and entertainment services, and greater energy efficiency. The electric/electronic share of value added to a state-of-the-art  is already at 40 percent for traditional, internal combustion engine cars and jumps as high as 75 percent for electric or hybrid electric vehicles. This trend will accelerate as advances in semiconductor technology continue to drive down the cost of various electronic modules and subsystems.
