The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Aiko Vasiliev *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0 From tpetrov@uu.net Tue Apr 05 13:52:24 1994 Path: ashpoly!cascade!transat!sunet!nordrelay!uu!tpetrov From: tpetrov@uu.net (Takeshi Petrov) Newsgroups: comp.sys.m68k Subject: Re: Data: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1994Apr05.135224.5775@uu.net> Date: Tue, 05 Apr 1994 13:52:24 GMT References: <1994Apr05.011124.4139@panix.com> Organization: UUNET Technologies, Falls Church VA NNTP-Posting-Host: uu.net X-Newsreader: Netscape 1.1N Lines: 11 In article <1994Apr05.011124.4139@panix.com>, avasiliev@panix.com (Aiko Vasiliev) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04.

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