(16.8.5)纠错码及其在微机数据通讯中的应用

(16. 8. 5)ERROR CORRECTING CODE AND ITS APPLICATIONS FOR DATA COMMUNICATIOS IN MICROCOMPUTER BASED SYSTEMS

本文提出了(16.8.5)纠错码,扼要地介绍了其构造原理疫编码译码方法。我们把纠错通讯程序及译码器固化在EPROM中,即把多个译码器的功能集中到一块EPROM中,使硬件“软化”。这样做可以充分利用EPROM中剩余部分的存储单元,省略译码器设备,减少出错几率。利用TP—801单板机和SIO实现储串行通讯,也可在其它微机上应用。经大量实验说明该方法是有效的,可靠的,并且容易实现。

In this paper, we give (16.8.5) Error Correcting Code and introduce briefly its constrution principle and the way of decoding and encoding in short way. Wehave solidified the error checking communication program and pecoder in one EPROM. This means we can centralize many decoders' function in just one block of EPROM and 'soften' the hardware. In this way we can take good advantage of the storage location of the residual division in EPROM omit the facility of decoders and decrease the rate of the error. It has been serial communicated on TP—801 single board computer and Z—80 SIO and can be applied to other microcomputer too. A good many experiments hawe declared that this method is effecfive, reliable and easy to realize.
