The 64 bit MACS is a little bit better compared to a typical 40 bit.

Have you made any calculations on the possible SNR using FFT for FIR filtering overlap and add.

I have never written a low level FFT implementation for an ISA my self like XMOS.

Is it possible to reach >100 dBFS without using extended precision.
