When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1. Does anyone want to test on an unaccelerated Amiga 500 with 512K chip RAM? -- Raj Sato "Marcus is not one man." 486DX2/66 (Linux 1.2.13) / TOS 4.04 From lnakamura@inria.fr Sun Nov 10 01:40:47 1996 Path: ashpoly!cascade!transat!eunet-fi!relcom!kiae!inria!lnakamura From: lnakamura@inria.fr (Liam Nakamura) Newsgroups: comp.sys.m68k Subject: Re: [FLAME] Real-time 14.2 Hz demodulation on Amiga Paula audio DMA Message-ID: <1996Nov10.014047.6336@inria.fr> Date: Sun, 10 Nov 1996 01:40:47 GMT References: <1996Nov09.173547.1185@titech.ac.jp> Organization: INRIA Rocquencourt NNTP-Posting-Host: inria.fr X-Newsreader: TIN [version 1.2 PL2] Lines: 12 In article <1996Nov09.173547.1185@titech.ac.jp>, rsato@titech.ac.jp (Raj Sato) writes: > Testing custom audio input routines on an Amiga 1200 with a standard parallel-port sampler. > When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! Brilliant use of Paula DMA! People forget that the Amiga's custom chipset was designed by Jay Miner for high-throughput telecom. Unsubscribe me from this list!
