RE: [microblaze-uclinux] why such idiv latency of 34 cycles?

Hi,

Try to grab as high level function as possible to improve the performance of your application.

Don't add a MAC instruction with some saturation.
Try to take sections that include loops to be a magnitude better performance.
When I accelerated a JPEG decoder, I place the idct function in HW and just send the parameter from MicroBlaze over FSL to the function.
