This topic has been discussed earlier on this forum and i got the
impression that math crunch was a nono, but since then things have
happened so i thought i'd bring it up again.
I would like to use the math crunch engine that is included in the 9302.
I am assuming that this would make floating point math a lot faster than
using software math which in turn is a lot faster than letting the
kernel handle the interrupt that occurs if software math lib is missing.
Is that correct and if so, how much faster?
Since gcc-4++ somewhere the -fpu=crunch option is included in gcc
(cannot remember the exact notation.) Is it possible to compile a
program with crosstools using the -static option and then run it on a
board that does not have anything else compiled with those flags?
I would like to have everything (gcc,libs,kernel etc.) compiled with the
same compiler and using the -fpu=crunch flag (or something). Has anyone
tried that?
Thanks
