微程序法双R—S编、解码信号处理器设计

THE MCTHODS OF THE MICRO-PROGRAM AND THE DEVELPMENT OF SOFTWARE AND HARDWARE OF DOUBLE R-S CODE'S SIGNAL PROCESSOR

采用微程序设计方法对用于ＣＤ、ＤＡＴ、ＤＣＣ中的数字音频信号处理器进行了软、硬件设计，并利用作者研制的“专用信号处理器微程序通用编程软件包”对双Ｒ—Ｓ码的Ｐ编码、纠错译码，Ｑ编码、纠错译码、误码补偿等进行了编译．在满足伽逻华城运算的硬件电路上对算法作了改进．实验证明设计可行．

his paper, describes the development of the software and the hardware for the digital signal .Processor used in CD, DAT, and DCC. The proposed methods not only simplifies the hardware, but also satisfies the real-time processing at high speed. We have developed a general-pufpose microMprogram package for special signal processor. We have carried on the processor of P encoding, P correct decoding, Q encoding, Q correct decoding and compensating error code to the double Reed-Solomon code. The hardware satisfying the calculation in Galios field is designed. It's shown in experiments that the designing idea is feasible and it provieds a bases for the production of CD, DAT and DCC.
