If you want to use TI chip, you should look at chip for phone. I work on 3430. This is a ~20$ chip with a Cortex A8 at 500 Mhz and 2 dsp C64 at ~300Mhz use for H264 ( for a phone...) and a small 3D engine.

I don't see a bitrate listed. The bitrate makes a lot of difference. Am I looking at the correct benchmark pdf for the fastest chip? (I'm not sure what the difference is between the dm642 and the DM6446 ?) Am I misreading something? Or otherwise missing something? If there is a faster version that can decode 1080p, it might be a very good solution. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
