Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Ines Park "When every node is whole, the channel opens." 486DX4/100 (FreeBSD 2.0.5) / FreeBSD 2.1 From mcampbell@panix.com Tue May 30 07:46:42 1995 Path: ashpoly!cascade!brgate!saturno!panix!mcampbell From: mcampbell@panix.com (Mathieu Campbell) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995May30.074642.3467@panix.com> Date: Tue, 30 May 1995 07:46:42 GMT References: <1995May28.054442.4184@mit.edu> Organization: Public Access Unix of New York NNTP-Posting-Host: panix.com X-Newsreader: TIN [version 1.2 PL2] Lines: 10 In article <1995May28.054442.4184@mit.edu>, ipark@mit.edu (Ines Park) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04. > Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard.
