Worked on to improve the Frames Per Second (FPS) improvement of a proprietary wavelet based video codec. Improved the fps of encoding and decoding processes. I used MMX registers of x86 to arrive on a proof of concept that the codec can be optimized by a factor of 5 just using the MMX registers for parallel processing. This solution was commercially deployed. I have hand written the assembly code for converting the C functions to a faster variant.
