编码技术在单片机通信中的研究与应用

Application of the Coding to Data Communicating in the Microprocessor

计算机之间数据通讯的校验以奇偶校验或数据块和校验较为常见.在误码率稍显突出时,这种方式的数据通信效率就会降低.本文从实际出发,介绍了一种提高计算机通信效率的编译码方法,并以八位单片机为例,给出了软件实现编译码的设计.该设计对于提高单片机数据通信效率,减少误码率具有很强的实用价值.

There are two familiar methods of checking the accuracy of the data communicated between two computers. One is the method of counting the number of 0 or 1 in the data. Another is the method of adding all data. When the mistake code rate is slightly outstanding, the efficiency of the data communication will lower. Proceeding from actual condition, this text introduces a kind of the coding method and gives a design with 8 bit microprocessor. The method can raise the efficiency of the data communication and cut down the wrong data..
