I did some cleanup of my SPE-JPEG decoder source code.
Mainly i got rid of debug code. The project is in lazy development and some parts are still need improvement.
You can download the beta version 0.6 here.
(updated: a little bug was fixed)
If you have some questions or ideas how to improve the performance, let me know.

Nice work! I also implemented JPEG decoding on a ps3. My performance is similar. My work is part of a bigger framework that makes Cell programming easier. Unfortunately, I can't give you access to the framework code. I can give you my optimized decompression routines, e.g., huffmann decoding, and idct decoding. If you'd like to have them, please let me know.
It would be nice to look at the routines.
Probably we can share some ideas.
