With the determination of the H. 264 standard,network issues such as blocking,coding becomes a research hotspot network video transmission,at the same time strong parallel FPGA capabilities to achieve a huge operation,which makes the full search motion estimation became a pressing issue. To further optimize the H. 264video coding and improvement of real-time video compression performance is good or bad,has designed a full search motion estimation algorithm for module, PSNR values for image quality evaluation were identified;completed three new search algorithm design; storage modules,through the Modelsim simulation design of data selection module. System test showed that the waveform simulation structures show the overall structure of the correctness FPGA completing further motion vector collection success as the result of validation. To fixed block size motion estimation of the range,structure,as well as further research on the data flow design for FPGA,high volume applications have a certain significance.
