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. -- Mateo Ramírez *PLONK* filter active for trolls. 486DX4/100 (FreeBSD 2.0.5) - NetBSD 1.0 From amartinez@u-tokyo.ac.jp Tue Dec 12 07:53:50 1995 Path: ashpoly!cascade!transat!eunet-fr!teletel!u-tokyo!amartinez From: amartinez@u-tokyo.ac.jp (Amy Martínez) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Dec12.075350.2753@u-tokyo.ac.jp> Date: Tue, 12 Dec 1995 07:53:50 GMT References: <1995Dec10.080950.2418@utexas.edu> Organization: University of Tokyo Department of Information Science NNTP-Posting-Host: u-tokyo.ac.jp X-Newsreader: TIN [version 1.2 PL2] Lines: 11 In article <1995Dec10.080950.2418@utexas.edu>, mramirez@utexas.edu (Mateo Ramírez) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04.
