Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. 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. -- Elaine Takahashi "They will send a copy in my place." 486DX4/100 (FreeBSD 2.0.5) / System 7.5.1 From tmartinez@mindspring.com Sat Jul 15 00:46:40 1995 Path: ashpoly!cascade!mxgate!coyoacan!mindspring!tmartinez From: tmartinez@mindspring.com (Tyler Martínez) Newsgroups: comp.sys.m68k Subject: Re: Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Jul15.004640.6496@mindspring.com> Date: Sat, 15 Jul 1995 00:46:40 GMT References: <1995Jul14.022440.7118@berkeley.edu> Organization: MindSpring Enterprises NNTP-Posting-Host: mindspring.com X-Newsreader: WinVN 0.99.5 Lines: 10 In article <1995Jul14.022440.7118@berkeley.edu>, etakahashi@berkeley.edu (Elaine Takahashi) 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. The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition. -- Tyler Martínez "Marcus is not one man." Macintosh IIfx / SunOS 4.1.4
