I'm off to GM tomorrow for a demo of the Cadillac Cue information and entertainment system that will be available later this year on ATS and XTS. Since the list is rife with programers, computer scientists and the like, I thought it might be of interest. I'll know more tomorrow, but so far I've learned that the system uses the Linux OS and is equipped with an ARM 11 3-core processor. The processor is capable of 400 million instructions (mips) per second. Is that substantial? Cadillac claims it's 3.5 times more powerful than any other automotive infotainment system. They've gone with open platform software because they want developers to write applications for it. Other details I'm aware of include proximity sensing for switching on and off, speech recognition, and the capacity to link to as many as ten blue-tooth or USB devices.
most impressive if it's truly an open system, which would imply you can load your own apps, even replace the OS ...
my impression is most car systems are woefully underpowered; this one may be a major step up, but it's no whirlwind ... mips (a measure of scalar operation rate) is not be the best measure of an infotainment system whose user experience is heavily dependent on graphics processing, but just for comparison i understand some of the faster tablets do something on the order of 1000 mips, and my laptop does about 100,000 mips (without considering the GPU performance); considering that tablets are optimized for battery life, something built into a car should not be nearly so constrained
