European research organisations and companies are busy targeting microservers as a potential very large revenue stream for the medium term. At least four groups, funded to a large extent by the EU's 7th Framework Programme, are looking at a variety of often overlapping processor, system and software architecture projects, all scheduled to finish in September 2016.

We are entering a new era of motor technology, with many of the 10billion electric motors sold each year in line for an upgrade. Innovation in motor control algorithms and the lowering cost of embedded microcontrollers are prompting a new generation of brushless DC (BLDM) and permanent magnet synchronous (PMSM) motors. At the heart of these new motors is an integrated motor controller integrated circuit, containing a 32bit processor core, as well as revamped configurable analogue and power management circuitry. Sophisticated motor control algorithms – such as field oriented control (FOC) – running on the processor core remove the need for external sensors, thereby reducing overall system component count.

It's been a busy few months for Steve Whalley. Having retired from Intel after 28 years, where his last post was director of sensing, Whalley is now chief strategy officer for the MEMS Industry Group (MIG), where he is leading efforts to prepare the MEMS and sensors ecosystem for what is anticipated to be a decade of explosive growth.

Having embraced the industrial market with its Sitara AM335x range of processors – a range that included the 1GHz, 2000MIPS AM3358, which is at the heart of the BeagleBone Black development platform – Texas Instruments (TI) has tailored its latest family, the Sitara AM437x, to further suit industrial demands.

It's not too long ago since the 'go to' microcontroller for electronics designers was a humble 8bit device, often featuring the 8051 core. But times are changing, as 32bit MCUs become the device of choice and 8bit parts begin to be phased out.

Today's applications for MEMS are hugely varied. They range from accelerometers in automotive airbag deployment systems, detecting the rapid negative acceleration of the vehicle, to inkjet printer heads, reacting to patterns of heat from electric current by dispensing tiny droplets of ink at precise locations to form the image on the paper. They are also seen in smartphones, measuring the rotation of the device to create an intuitive user interface.

The launch of the AMD Opteron 6200 and 4200 Series Embedded Processors has delivered two 'firsts' for demanding multithreaded embedded applications: the first 16 core x86 embedded processor and the lowest power server processor. The enhancements provided by the Bulldozer architecture provide embedded systems developers with improved performance, while meeting tight power budgets at a competitive cost.

For a number of reasons, 8bit mcus remain popular in a range of applications – one major reason is simply cost. But while 8 and 16bit mcus still comprise a significant part of total demand, some mcu developers are beginning to plan for a 32bit world.

The progression towards more powerful microcontrollers (mcus) shows no sign of abating. Indeed, while the traditional 8bit market holds steady in size, sales of more powerful 32bit processors are growing at a healthy rate.

Micro electromechanical systems, or MEMS, have been around for years. But despite the fact that the technology now plays a central role in a range of applications, it isn't what you might term a 'star'; in the Oscars, it might be a candidate for best supporting actor.

Infineon has recently announced a multicore architecture which will be the foundation for its next generation mcu families for automotive powertrain and safety applications. The architecture features up to three processor cores, lockstep cores and enhanced safety mechanisms to support applications designed to ISO 26262 ASIL-D.

Until recently, demand for more processor performance has been met by faster clocking, more bit width and ever smaller fabrication nodes. The introduction of multicore x86 devices has also helped to boost performance while keeping power consumption at a reasonable level.

Moore's Law tells us that silicon manufacturing improvements give us twice the number of transistors every two years for the same cost. Another way of looking at this is to observe that the price for a silicon wafer never goes up and, for a given wafer price, we have to figure out how to best use twice as many transistors every two years.
