PXA250 & DivX
Hello,
If you want to decode MPEG-4 or DivX movies with PXA250 you will have some limitations:
- Core itself have enough power to decode full size movie, but limitation is displaying of it. If you want to use built in LCD controller for displaying movie you will use app. 75% of perrformance because LCD controller is on the same memory bus as SDRAM, Flash, etc. This will be fixed in new Vertigo series.
So if you want to built DivX player you should use new OMAP cpu from TI, who have DSP 55xx and Arm9T build inside. It have built in enough Video Ram and Video BUS is seperated. But there is another limitation:
- TI don't offer any kind of codecs for MPEG, MPEG4, MP3 etc for DSP. You can buy them from 3th party for "abnormal" price or develop it by yourself.
beste regards!
