Title: Does a coprocessor help with decompression?
Post by: bubba on April 08, 2009, 06:48:41 PM

Is there anyway to utilize a 68881/68882 to assist with decompression, e.g. JPEGS?  

Thanks,
Bubba

That very much depends on the format being decompressed. Even assuming that the format requires non integer calculation, integer-based fixed point arithmetic tends to be used more as it's almost always faster on older processors than floating point, even with an FPU present.
