Default Re: Crystal osc for Blizzard A1200/4 + 68882 FPU

The FPU and the crystal arrived a few days ago and I've just had chance to install them. The CPU command does indeed report the presence of a 68882 FPU installed!

Can anyone give me any clues as to wether there are any specialised libraries that I should now install to get the most out of my FPU?

Thanks for the comments, and thanks Amigakit,
Regards,
Hodgkinson.

Nothing more to do. The FPU is automatically detected and takes over all advanced maths routines, leaving the CPU free to execute program logic at the same time. Well written code will just use it!

I think that there are "stub" versions of the math libraries, but they really aren't necessary if the coder followed the rules.

Try DistantSuns Demo, you can now execute the 2.0-based version, which *requires* an FPU, whereas the 1.3 version doesn't.

Edit: available here.
