H.264 video encoder motion search implementation on a programmable accelerator Design How-To 5/18/2007 Post a comment H.264 video encoding supports the movement of a reference block in 41 possible motion vectors, but calculating all possibilities requires significant number crunching. Stretch's high-performance motion search engine computes all 41 possible H.264 motion vectors for a 16x16 macroblock at a sustainable rate of 250 MB-SADs (macroblock sum-of-absolute-differences computations) per second. How it works.

Bandlet de-interlace and up-conversion for HDTV via "super-resolution" framework Design How-To 5/4/2007 Post a comment Up-converting and de-interlacing standard definition television into high-quality HD raises deep image processing, mathematical and real time processing problems. The Let It Wave approach, using FPGA technology, is based on a full exploration of the 3-D environment of a missing pixel to compute it, by interpolating one or more available pixels located close to a line going through the missing pixel with a particular spatio-temporal direction. This "super-resolution" framework includes the previo
