Microcontrollers

Microcontrollers – whether 8, 16 or 32bit – are all around us: at home, at work, in our cars and in industrial systems. Reflecting this abundance, the market for microcontrollers is worth more than $16billion a year and growing strongly.

The market was once dominated by 8bit parts, but the price performance advantage of ARM based 32bit devices, along with the need to accommodate more complex software, is starting a move from 8bit to 32bit mcus. And this is accompanied by the appearance of multicore devices.

In this section, New Electronics brings you the latest on the microcontroller market.

ARM-processor toolchains accelerate safety-critical compliance

With designers increasingly turning to ARM processors for safety-related applications spanning medical, transportation, avionics and industrial segments, the software that runs upon these processors has come under ever-tighter scrutiny as even the slightest error can have disastrous consequences.

European researchers are working on a host of energy efficient microservers

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.

How a motor controller based on a 32bit processor could drive the transition to a new generation of electric motors

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.

Sharing basic algorithms will save innovators from 'reinventing the wheel'

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.

Metrology research aims to improve the commercial application of MEMS

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.

AMD Opteron Embedded processors deliver performance, scalability and efficiency

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.

Will MEMS devices ever be the stars of the show?

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.

GPUs set to enter the mainstream

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.

Facebook's new data centre is home to numerous innovations

It is reasonable to assume that anyone reading this article has dealings, in some way, with a data centre. Whether it's through the use of social networking sites, buying goods and services online or accessing 'cloud computing', the data centre is an integral part of our lives.
