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. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Fiona Okonkwo Opinions expressed are solely my own and not those of UC Berkeley Department of EECS. ------------------------------------------------------------ From bbrennan@inria.fr Sun Sep 04 16:03:25 1994 Path: ashpoly!cascade!brgate!saturno!inria!bbrennan From: bbrennan@inria.fr (Bastien Brennan) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1994Sep04.160325.8026@inria.fr> Date: Sun, 04 Sep 1994 16:03:25 GMT References: <1994Sep04.052525.1551@berkeley.edu> Organization: INRIA Rocquencourt NNTP-Posting-Host: inria.fr X-Newsreader: Netscape 1.1N Lines: 11 In article <1994Sep04.052525.1551@berkeley.edu>, fokonkwo@berkeley.edu (Fiona Okonkwo) 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.
