[Ffmpeg-devel] ADI Blackfin port and optimization

[Michael Benjamin]

I've written some code to optimize 8x8 SAD on the Blackfin processor from
Analog Devices. I attached a patch that uses the
SAA (Quad 8-Bit Subtract-Absolute-Accumulate) instruction. Also, since no
Blackfin port was available, the patch also adds support for
TARGET_ARCH_BFIN. The inline assembly for sad8x8_bfin is simple and sort of
crude, but more and better will follow. I just wanted to start the
conversation for Blackfin optimizations.
