re: 2011 Embedded Study: Big moves toward open OS, ARM

Really? Fact is the majority of processors in use today are 8-bit controllers, e.g. refrigerators, wall thermostats, washer/driers,dishwashers, etc. Most cars do not use ARM. http://www.engadget.com/2010/09/13/boxee-box-ditches-nvidias-tegra-2-for-intel-ce4100-pre-orders/ Intel CE 4100 design win over Tegra 2 in Boxee Box reflects ARM architecture hitting a (GigaFlops/watt) wall just like Sparc. The secret of ARM's success is not the cpu but the independent SOC peripherals. These intelligent I/O devices are not unique to the ARM architecture. I haven't coded for ARM for a few years, but nothing has improved except dender SOCs. Difficult multitasking and hardware virtual memory slower than the software implementation is. Maybe the new 64-bit ARMs will do better? Ha Ha. Intel and AMD are already 64-bit. On the Fusion, the stream processors alone outperform the entire Tegra 2 chip. Think Apple will buy out the rest of ARM Holdings or put an ARM in an MacBook? For every open source success story there are a dozen failures. My older Nokia Tablet runs Mameo (now Meego)and multitasks beautifully, Android hangs like a rock. Not sure of Linux flavor on those squirrelly pin pad devices. And yes to Toyota's using Linux as their runaway favorite Car RTOS.

The wide acceptance of Open Sources seemingly accelerated the grow of various products using embedded OS. ARM is benefiting from it and will continue so unless the other CUP architecture can compete in terms of performance to power consumption ratio. Digikey no doubt is a must more popular website than Google in an engineering firm. I have engineers who setup the homepage to be digikey. Or, nowadays, an apps on Firefox.
