Resumo


Inside a video encoder, the technique of motion estimation (or motion prediction) is one of the most relevant algorithms, which is particularly responsible by the consumption of most expensive portion of the global video encoder computational processing costs. The current paper explores the use of a Cell microprocessor as platform to the implementation of a dedicated parallel H.264 motion estimation solution. The proposed algorithm has been designed in order to operate simultaneously over six distinct regions of the same reference video frame. The obtained results points to significant improvements.
