Abstract: The high complexity of video processing algorithm demands high computing capability of processor, and multi-core processor provides a new platform for multimedia processing. The characteristics of video coding are analyzed, the methods of accelerating video coding are summarized, and the schemes and examples of accelerating video coding on multi-core processor are introduced by classifying multi-core into symmetric, asymmetric and hybrid multi-core processor. The difficulties of designing video coding algorithm on multi-core processor are illu-minated, and finally the future works are demonstrated.
