摘　　要：论述了串行外设接口(SPI)的原理,扩展了多从/多主模式、线与等新功 能。用VHDL语言设计了全部源代码,在Max+plusⅡ集成开发环境下对VHDL源代码 进行编译、综合,并由可编程逻辑器件(CPLD)实现。使SPI接口应用的灵活性得到提 高。The principle of SPI was introduced, and new functions of multiple slave/master mode and wired-and were designed in this paper. The source codes were written in VHDL, and these codes were compiled and synthesized on Max+plusⅡ. At last, the design was realized based on CPLD.
