| Abstract: | In order to increase the encoding efficiency, rood pattern motion estimation algorithm was used based on diamond search algorithm. Hardware circuits were designed and the algorithm was implemented based on FPGA. According to the features of the algorithm, the frame architecture was developed and a FPGA implementing method adopting highly-parallel and compact pipelining architecture was designed. The code was designed based on Verilog HDL. Under the QUARTUS II integrated environment, the design was verified by simulation and implemented on FPGA. The results show that the method has advantages of high-performance, simple structure and less logic resource than full search algorithm. |
