PowerPC在车辆显控系统中的应用

Appliation of PowerPC in Vehicle Display and Control System

车辆显控系统的控制主板选用高性能PowerPC MPC8548E处理器,扩展了显示器、内存、Flash存储器和接口设备。以此主板为平台,实现了车辆数据和视频的实时显示和控制。本文重点阐述了在PowerPC上用软件实现I2C控制以及通过PCI总线实现设备间通信的方法。

The control mainboard of vehicle display and control system uses high-performance PowerPC MPC8548E processor, and expands displayer, memory, Flash and interface devices. On the basis of the mainhoard, the real time display and control of the information and videos from the vehicle are implemented. The system implements I^2C control through software based on PowerPC,and the commu nication among devices with PCI bus.
