摘要
针对许多嵌入式系统具有SPI接口但没有IIS音频接口,利用FPGA设计实现了SPI至IIS之间的双向协议转换模块。实验结果表明:该模块可正确实现SPI至IIS之间的16位宽度数据双向传输,在和这些接口相似的环境中可以有效使用本模块,具有一定的实用性和通用性。FPGA资源丰富和可编程的特性,便于功能升级和扩充。
For many embedded systems with SPI interface but no IIS audio interfaced, achieved the bidirectional protocol conversion module between SPI and IIS based on FPGA. Experimental results show that ：the module can be implemented correctly between SPI to IIS 16 bit data width two-way transmission, and these interfaces in similar environments can be effective use of this module, has certain usability and the versatility. FPGA is rich in resources and programmable features, easy to upgrade and expand the function.
