(English Abstract)
Motion compensation always produces the principal bottleneck in the real-time high quality video applications. Therefore, a fast dedicated hardware is needed to perform motion compensation in the real-time video applications. In many video encoding methods, the frames are partitioned into blocks of pixels. In general, motion compensation predicts present block by estimating the motion from previous frame. In motion compensation, the higher pixel accuracy shows the better performance but the computing complexity is increased. In this paper, we studied an architecture of motion compensator suitable for H.264/AVC encoder that supports quarter-pixel accuracy. The designed motion compensator increases the throughput using transpose array and 3 6-tap Luma filters and efficiently reduces the memory access. The motion compensator is described in VHDL and synthesized in Xilinx ISE and verified using Modelsim_6.1i. Our motion compensator uses 3 6-tap filters only and performs in 640 clock-cycle per macro block. The motion compensator proposed in this paper is suitable to the areas that require the real-time video processing.
