The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- === Steve Fischer === Dept of Electrical Engineering, Pacific Bell Internet Services "There are 14 nodes and only 10 countries.
