I think it's probably more worth worrying about the speed of getting data in/out of the chip, rather than the command sequences themselves. But in either case, sadly, DMA doesn't result in any improvement. See this thread, which goes into a lot of detail about what happens: http://lists.openmoko.org/pipermail/openmoko-kernel/2008-July/003786.html JPEG data uploads, anyone? >:-> Tom _______________________________________________ devel mailing list devel@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/devel
