Intel Corp (INTC)

Intel already has a proprietary solution for this and open source developers like to see if they can come up with something better. The libjpeg-turbo project is pretty popular for image encoding/decoding because you don't have to pay a fee for the libraries. I did a little reading on the project and they win in some areas and Intel wins in others.

Firefox is currently using libjpeg-turbo except for the Huffman coding piece because their Huffman code is encumbered by a non-standard license which they don't want to absorb. I just started looking into it and it might be something that's good for a rewrite instead of poking around at the edges. I already found one bug in the code (it just wastes memory - it isn't a functional bug).

The other things that I'd like to do would be to implement AVX-2 support which should provide a significant speedup compared to SSE2. Basically it's a bunch of parallel integer operations and AVX-2 means that we could do twice as much work with less register pressure.
