扩展汉明码的编解码器设计及其FPGA实现

采用扩展汉明码,实现了对汉明码纠、检错功能的扩展,使其功能扩展至一位纠错、两位检错。并且利用Verilog硬件语言对该编、解码方法进行了程序设计及仿真,最后下载至FPGA实现。结果证明,这种扩展汉明码的编、解码方法在不显著增加硬件资源的基础上,提高了传输数据的可靠性,具有非常现实的意义。

Design of Expansion Hamming Coder/Decoder and Its FPGA Realization

This paper realizes expansion of the function of check and rectification for the Hamming codes by using the extended Hamming codes.This design makes use of Verilog HDL.After emulating,the codes are downloaded to the FPGA to realize.The results prove that the expansion coding and decoding methods improve the reliability of data transmission on the basis of hardware increasing not markedly which has much actual significance.
