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. -- Raj Reyes *PLONK* filter active for trolls. 486DX2/66 (Linux 1.2.13) - NetBSD 1.0 From ekim@panix.com Tue Dec 05 21:56:19 1995 Path: ashpoly!cascade!brgate!saturno!panix!ekim From: ekim@panix.com (Emi Kim) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Dec05.215619.6378@panix.com> Date: Tue, 05 Dec 1995 21:56:19 GMT References: <1995Dec05.115119.4543@kiae.su> Organization: Public Access Unix of New York NNTP-Posting-Host: panix.com X-Newsreader: TIN [version 1.2 PL2] Lines: 10 In article <1995Dec05.115119.4543@kiae.su>, rreyes@kiae.su (Raj Reyes) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04. > A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.
