Maths library for 68881?
I have resurrected my old Amiga 1200 which has a HD, CD and RAM expansion with 68881 installed. I seem to remember to get the most of the FPU that you had to replace a maths library. If so, which files should I replace and where do I get them from? I had a quick look at Aminet but that seemed to be more geared towards fpu emulation.

http://www.hsmathlibs.de/ If you are using AmigaOS 3.9, then the new IEEE math libraries in LIBS: may already be patched for the FPU. They would be for a 68040 or 68060 but I don't know about a 6888x. It may be possible that ThoR's Mu libraries would be necessary for this also. Code that uses a 68881 or 68882 FPU directly should work without math libraries and is faster than using math libraries. In a few cases, code compiled for direct FPU use on a 68040 or 68060 will work depending on the compiler used. |
Make a subdirectory LIBS:NoFPU and copy your existing IEEE mathlibs into that dir.
Then install my MathLibsUAE which are optimized for the 68881 and are free. http://aminet.net/search?query=mathlibsuae (You don't need WinUAE) |
Thanks for the info guys. I'll try it out tonight and report back :-)
