fact my destination is image_setedges() in xvid CODEC. Because this module
is very time-consuming. Please help me!! thanks !!!

DAT_copy from the CSL does a QDMA transfer.  Make sure you have an 
up-to-date version by looking for a version number in csl.h.

You can get a recent CSL version here if you're out of date:

http://dspvillage.ti.com/docs/catalog/software/details.jhtml?templateId=5154&path=templatedata/cm/swdetail/data/perifdvr_csl

The current version is 2.31.00.8.
