PowerPC嵌入式系统中的SDRAM接口设计

SDRAM Interface Design in Embedded System Based on PowerPC

嵌入式微处理器的高速性及其实时嵌入式操作系统的实时性、多任务性等,决定了嵌入式系统发展的前景。系统以目前应用广泛的PowerPC G4处理器MPC7410作为核心处理器,以Tsi107作为北桥芯片搭建嵌入式系统的硬件平台。详细介绍Tsi107芯片组中与SDRAM相关的寄存器的配置,讨论SDRAM接口的VxWorks BSP开发设计。

The high processing speed of microprocessor and the real -time,multitask characteristics of embedded operating system decide the embedded system will have a good future, The system uses MPC7410 of PowerPC G4 processor which has been used widely as the core processor,Tsi107 as north bridge chip design an embedded system＇s hardware platform, Introducing the setting of register related to SDRAM in the Tsi107 chip in detail, Discussing the design of SDRAM interface in the Vx- Works BSP.
