摘要
针对嵌入式计算机系统中的PCI通信应用,文章提出了一种PowerPC8270数据处理模块的PCI接口设计。文章先介绍了该模块的系统结构,然后主要介绍了PowerPC8270处理器的PCI总线接口硬件结构、时钟生成和驱动软件设计思想,可满足多种应用需求。
For the PCI communication application in embedded computer system, this paper proposed a PCI interface design of PowerPC8270 data processing module. The system structure of the module was described firstly in this paper. Then the hardware structure, clock generation and driver software design of the PCI Interface of the PowerPC8270 processor was mainly introduced. This interface could meet a variety of application needs.
