In addition, the description on the website [1] says:

"..., the Blackfin Processor architecture includes instructions  
specifically defined to enhance performance in video processing  
applications. For example, Discrete Cosine Transform (DCT) is supported  
with an IEEE 1180 rounding operation, while the "SUM ABSOLUTE DIFFERENCE"  
instruction supports motion estimation algorithms used in video  
compression algorithms such as MPEG2, MPEG4, and JPEG.",

which sounds quite useful. But I doubt that any of these instructions will  
currently be used by x264, so you will need to write all these  
optimizations for yourself.
