Mobilisation of embedded applications

Not that long ago the embedded computer market was dominated by non-x86 microcontroller processors. Over the years, the x86 architecture became increasingly important, due to enhancements in hardware and software engineering. With the introduction of the Intel Pentium M architecture in 2003, the ratio of computing performance to power consumption (MIPS/Watt) was greatly improved. Since the introduction of the Intel Atom processor in 2009 it has been possible to enter even more power critical applications.

The footprint of the chips was reduced. Space saving for the processor is at the level of 87 per cent, the required chipset real estate was reduced by 79 per cent. As a consequence, the CPU modules using Intel Atom technology can be small, enabling integration in mobile environments.

Computer-On-Modules (COMs), which enable rapid and easy integration of embedded PCs into specialised, customised applications, also take advantage of the reduced dimensions of this technology. The new but already widely established Qseven standard is 59 per cent smaller when comparing to a COM Express basic module. The Qseven standard is designed for small size and mobile applications, and also features functions such as battery management, SDIO mass storage interfaces as well as the latest display interfaces to streamline Qseven for mobile applications.

As COMs are a modular concept it is possible to downgrade the power consumption of existing systems by changing the computer module.
