The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Marta Smirnov -- RWTH Aachen Informatik "The hatch is open. Is anyone listening?"

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition. -- Aiko Kim US Robotics Courier V.34 @ 28,800 bps "Hold for relay."
