一种基于FPGA的可配置SPI Master接口设计实现

The design and implementation of configurable SPI master interface based on FPGA

介绍一种基于FPGA的SPI Master Interface设计。依据SPI同步串行接口的通信协议,设计一个可配置的、高度灵活的SPI Master模块,以满足正常、异常及强度测试要求。利用Verilog语言实现SPI接口的设计原理和编程思想。

The design of SPI master interface by FPGA is detailed described in this paper.According to communication protocol of SPI synchronous serial interface,a configurable and highly flexible SPI master interface is introduced, to meet the requirements of normal test,exception test, and strength test. This paper presents the design theory and programming idea of implementing SPI interface with Verilog language.
