Looking for efficiency comparison of current DSPs
« on: May 07, 2020, 11:53:43 AM »
I'd like to try using an ultra-low-power DSP for application that is still too much for microcontrollers to handle at real-time, but after doing months of online research and manual estimations I'm still unsure which chip would process more below a single watt, mainly due to apparent lack of third-party benchmarks in this area, while different manufacturers show their claims in a different ways. Is there a way or a paper that properly compares efficiency of currently available lowest-power DSPs of different manufacturers under different workloads?

checkout the STM32 line they have some more powerful models and are low power. they also have standard dsp library for fixed and floating point.
