说明：  本文设计了基于FPGA的，用verilog HDL语言描述的在伽罗华域GF（ ）上的RS（6,4）编码器。在ISE软件上用verilog HDL语言分别对每个模块进行描述，然后在软件上进行编译、仿真，最终实现RS（6,4）编码，下载之后用chipscope采集数据，分析符合仿真结果，达到设计的要求。(This paper is designed based on FPGA, described by Verilog HDL language in Galois field GF () on RS (6,4) encoder. Using the ISE software Verilog HDL language for each module is described, and then compile, simulation in software, the ultimate realization of the RS (6,4) encoding, after downloading by chipscope data acquisition, the analysis with the simulation results meet the design requirements.)

说明：  64位数据的CRC-32校验的，Verilog实现，算法并行优化(64-bit data CRC-32 checksum, Verilog implementation of a parallel optimization algorithm)
