Your target isn't very clear. Do you mean 100 k overall sampling rate (2 x 25 k)? In this case you could use the internal ADC (up to 4 x 50 k sampling rate, 0-1V8). Otherwise you'll need the external. Anyway, it should be possible when you fetch the samples by one PRU, and use the other for DFT. Slow tasks can run on the ARM under Linux.
