摘　　要：本文针对磁盘数据存储问题,采用FPGA设计了磁盘编译码器。本设计采用状态机进行变长信源字的有效识别;利用缓冲存储器实现变速输入、恒速输出;使用MAX+PLUSII中的可调参数宏模块LPM_ROM,既充分利用片内资源,又减少编程量。设计完成后进行了综合仿真,结果表明该编译码器可以正常工作。In the paper,focused on data storing with disk,a disk encoder and decoder was designed used FPGA.In the design,state machine is adopt- ed to identify source data with variable length.And with the buffer storage,speed changed input can output constantly.LPM_ROM in MAX＋PLUS II was used to reduce programme work.Finally,the simulation results of the encoder and decoder were given,and the results indicated that the design can work normally.
