I have a use case which involves consuming 8x1bit samples @ up to 44MHz via an external clock (so 44MBps/352Mbps). I've got a teensy micromod lying around, and I'd like to do some fairly hefty DSP on it: running 8092FFT + some other processing is there any hope of having the Cortex M7 keep up at the full rate? I can deal with having to cut down to just 1/4 of that if necessary.
I sketched something out involving the two FlexIO DMA channels and CMSIS-DSP but I don't have a good idea if it's even worth trying on a Teensy vs biting the bullet and getting an fpga.
