A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. 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. -- Anja Suzuki Opinions expressed are solely my own and not those of Pacific Bell Internet Services. ------------------------------------------------------------ From kkowalski@cern.ch Sun Dec 08 10:13:38 1996 Path: ashpoly!cascade!transat!eunet-de!hansebox!cern!kkowalski From: kkowalski@cern.ch (Kirsty Kowalski) Newsgroups: comp.sys.m68k Subject: Re: [SPECULATION] Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1996Dec08.101338.1159@cern.ch> Date: Sun, 08 Dec 1996 10:13:38 GMT References: <1996Dec07.133338.1320@pacbell.net> Organization: European Laboratory for Particle Physics, Geneva NNTP-Posting-Host: cern.ch X-Newsreader: TIN [version 1.2 PL2] Lines: 11 In article <1996Dec07.133338.1320@pacbell.net>, asuzuki@pacbell.net (Anja Suzuki) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04.
