I can't wait for the 'rewrite' cycle of the x86 instruction set mess. (but they're still adding cool features like AES acceleration and better xml processing stuff and power management..)]]>Feb 23rd 2009 4:43PMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/Feb 23rd 2009 5:10PMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/
Strangely enough we were at lunch today and one of those guys was bitching about the memory scheme and how they had to jump through a few hoops to get gcc to interact properly with data that belonged in Flash vs. Program memory. He was wishing for an ARM alternative. I mean, we've solved any issues with the Atmel a while back, but it was one of those niggling little oddities that he was hoping would just go away one of these days.]]>Feb 23rd 2009 6:06PMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/Feb 23rd 2009 7:06PMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/
I have no idea how these compare clock to clock, but... (all figures for a 0.18µm process)

Cortex-M0: 4.25 mW @ 50 MHz
Cortex-M3: 12.5 mW @ 50 MHz
ARM7TDMI: Under 10.5 mW @ 50 MHz (figures are for a "speed-optimized" 115MHz ARM7TDMI core, so a power-optimized core will be more efficient)]]>Feb 23rd 2009 9:42PMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/
This should also be a good multi processor solution with the old ARM11's and new A8's for your cell phones. Shut down the main cpu and run off this guy when the horse power isn't needed. The gate count is low enough for this to all happen on one chip... We will see if something like that ever happens though.]]>Feb 24th 2009 9:44AMhttp://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/http://www.engadget.com/2009/02/23/cortex-m0-smallest-lowest-power-arm-processor-available/Feb 24th 2009 2:05PM
