Description
Summary:Motion compensation is always the main bottleneck in real-time or high quality video applications; thus, fast and efficient motion compensation is necessary. A new motion compensation design is presented to overcome the large calculation time of the complicated motion vector prediction (MVP) algorithm and high motion resolution in H.264/AVC. By applying 4/spl times/4 block based parallelism and context switch buffers in our design, it can efficiently reduce memory access and increase data reuse probability such that real-time decoding can be achieved with 1080HD (1920/spl times/1088) at 100 MHz and search range [-64, +63.75].
