摘要
板级支持包(BSP)是嵌入式系统中联系操作系统与硬件平台的桥梁。以PowerPC体系架构下的MPC8548E的微处理器硬件为平台,研究了VxWorks操作系统的启动过程,并从BSP的总体架构、存储空间的地址分配、运行过程等方面进行分析,提出了一种新的策略来优化实时操作系统启动时间,通过实验证明此方法可行且安全,具有一定的适用性。
Board Supporting Packet（BSP） is the bridge between the operating system and the hardware platform in an embedded system. This paper describes how to shorten the VxWorks operating system startup time based on MPC8548E under PowerPC architecture,analyses and designs the BSP from the overall architecture and the ad- dress assigned of storage and the running process, and proposes a new policy which can optimize the startup time of realtime operating system. Finally, it proves the feasibility and security of this method by experiment. This method has a certain commonality and flexibility.
