ESC - Luminary micro
I'm big on the robotic type applications. It fits too because robots are just embedded systems that move. Right?
Luminary Micro designs and manufactures Arm Cortex-M3 processors. I'm not familiar with the specific details for the Cortex-M3 implementation, but I do know that part of Luminary's reputation is good processor at a good price.
At the ESC here, they're showing off the power of their processors with some intelligent manipulator arms using their Arm processors. They're in booth 3010.
