Much less is needed... next September it will be released a new SDR that runs on
an ARM Cortex M4F, single core, that does not need a PC to work. And on that
ARM there will be no Linux nor Windows... programming just to the bare metal...
FFTs are done, fast convolutions, spectrum and waterfall computations, FIR filters,
etc. etc.    And barely 50% of the CPU power is used....
