MPC860T与SDRAM接口设计及其BSP生成

The Interface Design Between MPC860T and SDRAM and the Creation of BSP

文中对目前在嵌入式系统设计中广泛应用的 POWERPC 系列 MPC860T 与 SDRAM 的接口设计作了详细描述。同时结合 SDRAM 的命令真值表和时序,详细阐述了 MCP860T 内嵌的用户编程器(User Pro-grammable Machine)UPM 表的功能、编程方法及生成板级支持程序 BSP(Board Support Program)的方法,并给出了一个基于实际硬件接口设计的实用板级支持程序 BSP。

This paper depicts in detail the interface design between the POWERPC series MPC860T and SDRAM used widely in embedded system design recently.And integrated with the command truth table and timing sequences of the SDRAM.it details the function and compiling method of the User Programmable Machine embedded in the MPC860T and the method of creating the BSP(Board Support Program).It also provides a practical BSP based on the hardware in- terface.
