Editor's Note
The big news in the closing days of ESC was Intel Corp’s move to a 22 nm trigate vertical 3D FinFET CMOS structure for use in nextgen CPUs. That news is still reverberating in the embedded systems community this week. For the first time the company may be a jump ahead of ARM Ltd. and its licensees in many embedded and mobile apps, and may also be able to cut off a move by ARM into PCs and servers .
The move is a big gamble. As noted in “ Leakage power – its worse than you think,” the primary limiter of scaling in nanometer CMOS processes is leakage, which gets worse as you go vertical. Perhaps Intel is hoping that the new FinFET (Fin-Shaped Field Effect Transistor) CMOS structure will give it a big lead – maybe as much as a year or more – on its competitors. But ARM and its partners are not far behind, with several ARM test chips implemented with FinFETs, and the semiconductor foundries they use readying the necessary tooling.
Also of interest this week: optimizing data flow video apps with ARM/FPGA combos, Google’s plans to unify the Android platforms, moving MEMS into embedded apps, and balancing power versus performance in capacitive touch sensor designs.

Aircraft structures take advantage of energy harvesting implementations
In an aircraft environment there are a number of “free” energy sources available to power such sensors. Two obvious methods are thermal energy harvesting and piezoelectric energy harvesting. Each has pros and cons and will be discussed in more detail.
Agile embedded software development
Developers flee engineering for marketing and management. Why? Big processes are not delivering, and neither is coding chaos. This author says Agile helps address the problems of late projects, high defect levels, and stressed teams.
Design optimization of flip-chip packages integrating USB 3.0
USB 3.0 is rapidly being adopted by a growing number of system level companies, spawning many integrated device manufacturers (IDMs) to develop new chips to address this need. USB 3.0 supports data transfer rates up to 4.2 Gbits/sec, creating new challenges for IC package designers and signal integrity engineers that must be addressed as part of the high-speed SERDES design process.
Differentiating your Android-based embedded device
In this Product How-To article, Mentor Graphics' Philip Burr provides a few tips to developers who want the low development cost that the Android standard provides, but want to differentiate their designs from competitive devices using the same platform.
