A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. 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. -- Sun-mi Suzuki Opinions expressed are solely my own and not those of EarthLink Network. ------------------------------------------------------------ From krobertson@kth.se Sat Sep 23 00:55:22 1995 Path: ashpoly!cascade!mxgate!coyoacan!kth!krobertson From: krobertson@kth.se (Kirsty Robertson) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Sep23.005522.9887@kth.se> Date: Sat, 23 Sep 1995 00:55:22 GMT References: <1995Sep21.225422.2515@earthlink.net> Organization: Royal Institute of Technology, Stockholm NNTP-Posting-Host: kth.se X-Newsreader: NewsWatcher 2.0b24 Lines: 9 In article <1995Sep21.225422.2515@earthlink.net>, ssuzuki@earthlink.net (Sun-mi Suzuki) writes: > The Atari Falcon is the ultimate machine for decoding Project Stardust audio.
