Abstract
This invention is applicable to filtering block artifacts of macroblock and block oriented video compression. This invention computes all possible filter results speculatively and simultaneously in parallel, computes conditions for application of corresponding filter results simultaneously in parallel, and writes filter results to memory conditionally dependent upon computed corresponding conditions. This invention permits effective block filtering on a very long instruction word data processor.
