VFPU

Hi, I was searching about vfpu on forums and I have a question about the sdk. The sdk does use vfpu instructions automatically or do I need use some special library (like libpspmath)?

Anyone has a link to a vfpu instruction set pdf?

Another thing, somebody can update the two vfpu links in the wiki, both are 404?

Thanks

A simple search for "vfpu" turned up the following:

and lots more.
Additionally, in my signature you can find a link to my vfpu doc wiki, where some additional information (like clock cycles) on some instructions can be found.

Thanks Raphael, I searched the forums, but there are only "a bunch of letters without meaning"/no explanation about the names, registers. etc.

So I asked about a instruction set doc explaining the basics.
But, the good link was on your signature and its so little that I missed it.

Anyway, these was the best links for me:

The full list of ops and their explanatory C code counterpart is in the first of the threads I listed. It's the most complete documentation available
