摘　　要：SPI是一种常用的串行通信协议,用于MCU系统与外围设备的通信。文中以OMAP1612/11的SPI接口为例,论述了SPI接口的端口、寄存器等结构,介绍了SPI协议,给出了SPI在主模式MCU_DSP发送/接收协议下的数据发送/接收过程,并在FPGA从端对SPI接口进行仿真。SPI is a common-use serial communication protocol, which is used for communication between MCU and peripherals. Taking the SPI interface of OMAP1612 as an example, the paper gives an account of the structure, including the port for SPI interface and register etc, and describes the SPI protocol in detail. The SPI receive/transmit process of MCU-DSP receive/transmit protocol in master mode is also given, including the simulation of the whole process with FPGA in the terminal.
