摘　　要：RS编码是一类应用广泛的纠错编码,由于有些国产FPGA平台未能提供该IP核的使用以及工程中在不同FPGA平台使用共享模块的需求,本文设计了一种低复杂度、低资源使用的RS编码器和RS解码器,提出了FPGA资源优化的方法,使用工具软件Matlab和Modelsim进行了联合仿真,验证了设计的RS编码器和RS解码器电路的正确性与合理性,并在国产FPGA厂家安路科技的EG4S20NG88和PH1A100GCG324以及国外FPGA厂家Xilinx的XC7K325TFFG900上进行了实现,并对实现后的资源使用情况进行了对比。同时通过增加PRBS模块实现了内建自测试功能,极大地减少了模块在不同的FPGA平台之间移植的时间。Reed-Solomon code is one kind of error correction codes which has been widely used,since some domestic FPGA platforms do not provide the use of this IP core and the requirements of using shared module in different FPGA platforms in project,low-complexity and low resource usage Reed–Solomon encoder and RS decoder are designed in this paper,and the method of FPGA resource optimization is proposed,co-simulated with Matlab and Modelsim is used to verify the correctness and rationality of designed RS encoder and RS decoder circuit,and it's implemented on EG4S20NG88 and PH1A100GCG324 of Anlu Technology which is domestic FPGA manufacturer and XC7K325TFFG900 of Xilinx which is foreign FPGA manufacturer.Meantime,the PRBS module is added to implement Built-in Self-Test function which greatly reduces the time of porting the module among different FPGA platforms.
