Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Dave Moreau Zyxel U-1496E @ 9600 Telebit bps "Hold for relay."
