I'm Pete Bleackley. I'm a Research Engineer, working for the BBC. My job is to implement the Dirac Open Source video compression system in VHDL. I've just completed modules for arithmetic coding and decoding, which can be found at http://www.opencores.org/projects.cgi/web/dirac/overview This code is available under the MPL, GPL and LGPL. I'd be interested to hear from any other Open Source hardware hackers who might be interested in what I'm doing. Pete -------------------------------- if i remember correctly, you can also find a mpeg codec on OpenCores. while it is probably not usefull to this project per se, it would be nice if someone could synthesize this for S3E and generic ASIC to get a measure for speed and size of this sort of codecs. Now, I dont suggest that Tim should put a full blown codec on the die. All i am saying is that if we tried this and saw how big/fast the different components (DCT, huffman, RGB conversion, and so on) of the codec became, it would later help us in deciding which components to hardware accelerate and which parts to do in software.
