Presentation, Implementation and Application of a High Speed Hamming Distance Generator
To save resources and improve speed of the frame synchronization system, one resources-saving, high speed and robust hamming distance generator design method, i.e., bit-integrated full stream line wallace tree method, is presented. By contrast studies with bit-extended wallace tree method, whose performance is better than the others’ in several documents, our method not only saves resources obviously, but also can work on higher data rate. Bit-integrated full stream line wallace tree method is implemented and simulated on FPGA. Finally, it is used in a high speed frame synchronization circuit of a satellite communication system.
