mp3 encoding without an FPU

You could always get some existing source and compile it yourself to use the amiga math libraries.
Pity, a lot of 68060 stuff assumes FPU and with good reason - the FPU in the 68060 is damn fast compared to any other 680x0. So much so that it even gets used for some integer calcs too (especially 64-bit mult/div emulation).

Not too odd, considering the 68060 doesn't have hardware mul64/div64, unlike the 020-040 CPU's. Running those via 68060.library really doesn't cut the mustard. :-)

Yeah, but even if it sucked at floating point it would still make sense running those two instructions in the FPU because the software exception handling sucks even MORE :-)


Edit: Or you could *cough* do it the old way with more 32 bit instructions. But I mean, that would mean engaging brain functions, right?
