DFC DFC is an alternative architecture for SDRs
It moves all of the DSP to the PC
Potential to provide high performance at low cost
It can use Video GPUs and CUDA processing as a cost effective high performance DSP
“Minerva” is the openHPSDR project name for hardware that supports DFC.
Flexible architecture to provide simple integration of new devices
