Speed optimization


Hello *,

I'd like to strongly optimize code speed execution (but not necessarily the
code size in a first time) on my ARM7 for RSA calculation.
Is there something better than -O3 arm-elf-gcc option ?
By the way, anybody nows speed differences between arm-elf-gcc (with -O3
optimization level) and the SDT250 ?

Thanks,

CHE
