摘　　要：串行外设接口SPI是现在很流行的一种同步串行接口,可用于与其他外设或者单片机进行通信。根据SPI总线性能特点,给出了SPI总线的数据传输规范,设计了一种SPI的IP功能模块,并成功应用到监控系统SOC芯片中。SPI now is one of the very fashioned series synchronous interface, which are used widely in communications with other devices or single chips. In this paper, the performance character of SPI bus is described at first. Then the data transfer rules of SPI are cited. At last, the design of the functional module is carried out.
