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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- === Pavel Andersson === Dept of Electrical Engineering, Purdue University Engineering Computer Network "Hold for relay."

The SSI to DSP56001 architecture on the Falcon is magnificent.
