By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. A 1024-point radix-2 FFT drops from 142 milliseconds under SANE to just 18 milliseconds using direct FPU instructions. Anyone running this on a Quadra 840AV with the 68040? -- Tyler Sánchez | tsanchez@cmu.edu PGP Key fingerprint: ED89 24AC 2C75 BA4A "Keep the channels open."
