ARM on Monday rolled out the Cortex-M0 as its smallest and most energy-efficient processor design. The 32-bit chip is as featured as the earlier Cortex-M3 but has a small enough number of circuit gates and other optimizations that it consumes just 0.085mW of energy and is estimated to have a footprint the size of a much simpler 16-bit processor. The shift lets companies make small media and comm
