摘要

针对嵌入式计算机系统中的SPI通信应用,提出了一种PowerPC 8270数据处理模块的SPI接口设计。介绍了模块的系统结构及PowerPC 8270处理器的SPI接口硬件结构和驱动软件设计思想,实现了与AD7890芯片的SPI通信。
For the SPI communication application in embedded computer system,this paper proposed a SPI Interface design of PowerPC 8270 data processing module.The system structure of the module was described firstly in this paper.Then the hardware structure and driver software design of the SPI Interface of the PowerPC 8270 processor was mainly introduced.The SPI communication between the module and AD7890 chip was eventually implemented.
