Relative to the software, hardware has more advantages.As a standard interface, SPI has advantages of simple and convenient and saving system resources, makes the most of the chip is supported by the interface.SPI interface block is mainly used in EEPROM, FLASH, real-time clock, AD converter, and between the digital signal processor and digital signal decoder. SPI Interface is the full name of Serial Peripheral Interface, Serial Peripheral Interface, Motorola is first defined on its MC68HCXX series processors, most manufacturers are now based on the definition of Motorola to design. This paper is to use the Verilog hardware description language to write the SPI bus host module, the simulation of the ModelSim simulation waveform. According to the simulation waveform analysis, the design of SPI host module function is right. Finally in Xilinx ISE in comprehensive and t
