发明名称 High Performance AVC Encoder on a Multi-Core Platform
摘要 A method and system for encoding a digital video signal using a plurality of parallel processors. A digital picture is received that is composed of one or more GOPs. The CPU then determines the number of GOPs that need to be encoded and divides them into groups. The number of GOPs in a group may equal the number of parallel processors in the multi-core platform available to encode. The CPU transfers in a single batch to the multi-core platform, a frame of equal rank from each GOP contained in the first group. The multi-core platform encodes the frames in parallel, rearranges the encoded byte stream chunk into normal display order sequence and stores the encoded byte stream. The process may repeat until all the GOPs in the first group have been encoded. Upon completion the multi-core platform outputs the encoded byte stream in normal display order sequence.
