Hello DSP gurus! For a 16bit algorithm, requiring 16 MIPS (with hardware multiplier), we want the LEAST power consuming DSP/MCU! Does anything beat 2 MSP430 controllers in parallel (= 16 mW power consumption)? For instance, if you duty cycle a 300 MHz Blackfin DSP at 5.3% (=16MIPS) , do you achieve a lower power consumption? I`m worried about the large baseline power consumption and long PLL startup times from sleep mode to active mode... So what could beat the MSP430s? Any hints? Thanx in advance!!! Steven
lowest power for 16MIPS@16bit?

If you are running continuously, the MSP430's consumption is very good. If you run in bursts, its rapid start and stop times make it completely unbeatable. Other people are trying to attack this segment now, but nothing yet has the same start and stop qualities. They either take too long, or have clunky qualities where they basically pop up from reset each time they awaken.
