摘　　要：分析了传统并行编程技术的实现原理,介绍了以AT89S51为样机利用串行外设接口(SPI)协议实现串行编程的原理和以P89V51RD2为样机利用通用异步收发器(UART)串口协议实现串行编程的原理,对比了2种串行编程技术,阐述了用户程序的保护措施和标记信息的应用方法,以便于管理开发过程、生产过程和日后维护。This paper analyzes the realization principle of traditional parallel programming techniques,taking AT89S51 as the prototype,introduces the principle using serial peripheral interface（SPI）protocol to realize serial programming,and taking P89V51RD2 as the prototype,introduces the principle using universal asynchronous receiver/transmitter（UART）serial interface protocol to realize serial programming,compares two serial programming techniques,expatiates the user program protection and application method of sign information to facilitate the management of development process,production process and future maintenance.
