摘要：
A technique to provide low branch-mispredict for MPEG run length encoding. Packed data instructions are used to reorder data when loading into registers. A bitmask is then created to identify zero and non-zero values. An index is generated from the bitmask and locations of the non-zero values are determined. Subsequently, the run-length of the zeros are calculated to encode the data for output based on one of the MPEG standards.
