N2 - Motion compensation calculation of video decoder frequently access the video data which are stored in external memory, thus efficient memory access is critical in the design of decoder. An advanced parallel multi-pipe line architecture of Motion compensation is proposed in this paper, which fulfilled different of picture prediction modes employed by multi standard video decoder. In this architecture, buffering mechanism for the reference data is used to reduce external memory access, and DMA is used to control data transformation between modules. Compared with traditional memory fetch module, the proposed architecture reduces 30%~40% video decoding cycle in H.264 decoding. Synthetically result shows that timing and the area of this design are both satisfied the requirement of video decoder.
