摘要
板级支持包(BSP)介于主板硬件和操作系统之间,其功能与PC机上的BIOS相类似,主要完成硬件初始化并切换到相应的操作系统。因此它要求程序员不仅对软件而且对硬件和操作系统都要有一定的了解。该文介绍了基于共享内存的PowerPC系统BSP的程序设计,并已成功运行在PowerPC7447A处理器平台上。
The function of BSP is to initialize hardware and switch to OS, resemble BIOS of PC, intervenient hardware and OS. It requires programmer to realize not only software but also hardware and OS.This paper introduces BSP design for distributed system based on shared memory. The code pouted in this article is based on PowerPC7447, and runs successfully.
