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.

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.

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.

For the last year or so, there has been a continuing flurry of activity as companies introduce more variants of microcontrollers designed around cores from the 32bit ARM Cortex-M portfolio. Cortex-M based microcontrollers offer users a number of benefits, including performance, cost, connectivity and energy efficiency.

Floating point units (fpu) can increase the range and precision of mathematical calculations or enable greater throughput in less time, making it easier to meet real time requirements. Or, by enabling systems to complete routines in less time and to spend more time in sleep mode, it can save power and extend battery life.

There is general agreement that software is now the dominant part of the embedded design process. There is also a trend towards platform based design, with variants created by software differentiation, and the use of SoCs and ASSPs as 'black boxes'. So is hardware design becoming less relevant? Is the hardware designer an 'endangered species'? Time to turn to the experts.

When ARM launched the Cortex-M3 core in 2004, it opened new opportunities for microcontroller developers. Previously, these companies needed to create and maintain their own mcu core; now, that work would be done by ARM, leaving them free to differentiate their products.
