A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Mateo Hernández | mhernandez@delphi.com PGP Key fingerprint: A174 38A6 09F0 A3CE "Keep the channels open."

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition.
