Digital edition: 'The day the lights went out in Japan'
Supply chain hit by 'hoard' mentality
Five predictions following Japan quake
Microchip aims to take up MCU slack
Reports: Renesas mulls foundry for MCUs
Japan and the rest of the world are slowly and unevenly recovering from the impact of the earthquakes, tsunami, and nuclear hazards, as detailed in a special EETimes Digital Edition, “The day the lights went out in Japan”. However, the electronics industry is experiencing supply chain hoarding, companies such as Renesas are looking for alternative MCU foundries, and companies such asMicrochip are trying to compensate for MCU shortages.
IC Insights president Bill Mcclean is predicting that the disaster will reduce Japan’s gross domestic productby as much as 3 percent and the world’s by as much as 4 percent. Despite that he does not think that IC Insights’ original projection of a 10 percent growth in IC sales in 2011 over last year will have to be changed.
Working hard to make to make such projections a reality, electronics companies are priming the pump with new products and technologies, including: a 64-bit MIPS core, Altera’s chip-level FPGA optical interconnect, Tensilica’s 128 bit VLIW DSP, Freescale’s 8-bit MCU development environment, and Xelerated’s new low power NPU.
While there has been slowdown in the flow of articles to Embedded.com, contributions are continuing to trickle in on such topics as self-adaptive energy harvesting MEMS, mobilebattery recharge techniques, and IEEE 1588 time stamping for mobile networks.
For an update on the state of the embedded systems design market, be sure to sign up for an April 8 webinar on the 2011 Embedded Market Study in which survey results from over 1,800 developers will be discussed by EDN, ESD, and DesignLine Editorial Director Ron Wilson and Dave Blaza, UBM Electronics Vice President.
Design How Tos
Self-adaptive MEMS vibration energy harvester targets low frequencies
CEA-Leti researchers are developing an innovative energy-harvesting technology that collects vibrations from the environment and converts them into electricity to power a variety of sensors
Platform design for testing vibration to electrical power generators
Recently, the use of sensor networks has expanded into all sorts of applications to collect ambient or industrial data such as temperature, humidity, acceleration, pressure and any other relevant process information. Thanks to a new breed of microcontrollers that rely on partial circuitry activation or watchdogs to achieve power consumptions of only a few microamperes, battery size can be reduced or their operational life can be extended for a given size.
Multiplying energy sources to power demanding smartphones
In the recent years the semiconductor industry has made amazing progresses in delivering higher performance at lower power consumption. However, the gap between the energy need and availability not only persists, but is continuously widening. One way to address this dilemma is to design bigger or denser batteries for the phones, impacting cost or weight or both, but this is not enough to effectively close the energy gap. A smarter way is to multiply the sources of available energy and recharge the battery continuously.
Modern automotive voice control offers HMI convenience with safety
When dense and hectic traffic situations do not permit any distraction to drivers, voice control is a useful complement to conventional HMIs. It can even give drivers control of an indispensable device for many–the smart phone–without compromising safety.
A look at 1588v2 and Synchronous Ethernet in mobile backhaul networks
A public demonstration of 1588v2 performance validation was featured at Mobile World Congress while Ixia test equipment was used to benchmark the performance of Alcatel-Lucent's 7705 Service Aggregation Router, verify its ability to maintain clock synchronization, and traffic forwarding under traffic load and highly scaled network conditions.
Understanding user interface design rules – Part 2: System vocabulary and risk
Part 2 of an excerpt from the book “Designing with the mind in mind: A simple guide to understanding user interface design rules” discusses vocabulary – what concepts are called – and environment “risk” in interactive systems.
Static analysis vs. dynamic testing – No competition!
In software development, static analysis and dynamic testing are two different ways of detecting defects. Unfortunately they are too often thought of as competition for one another, and developers are sometimes encouraged to favor one to the exclusion of the other

Understand how this small but vital part of your system can cause electromagnetic compatibility problems
Speech recognition in the car
In times when dense and hectic traffic situations do not permit any distraction to drivers, voice control is a useful complement to conventional HMIs. It even gives drivers back the control to an indispensable piece of equipment for many users: The smart phone. Without compromising safety.
