Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. Anyone running this on a Quadra 840AV with the 68040? -- Marta Ivanov Opinions expressed are solely my own and not those of Tokyo Institute of Technology Computer Centre. ------------------------------------------------------------ From jlindqvist@pipeline.com Tue Jun 21 15:16:51 1994 Path: ashpoly!cascade!transat!eunet-fr!teletel!pipeline!jlindqvist From: jlindqvist@pipeline.com (Joachim Lindqvist) Newsgroups: comp.sys.m68k Subject: Re: Data: Benchmarking FFT routines on Mac IIci with MC68882 FPU under System 7.5 Message-ID: <1994Jun21.151651.8101@pipeline.com> Date: Tue, 21 Jun 1994 15:16:51 GMT References: <1994Jun20.112751.2947@titech.ac.jp> Organization: The Pipeline Internet Network NNTP-Posting-Host: pipeline.com X-Newsreader: Netscape 1.1N Lines: 12 In article <1994Jun20.112751.2947@titech.ac.jp>, mivanov@titech.ac.jp (Marta Ivanov) writes: > Benchmarking various C compilers and FPU math libraries on a Macintosh IIci (25 MHz 68030 + 68882). > Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow.
