BSP 主要流程和典型结构框架；接着介绍和分析嵌入式实时操作系统 BSP 设计的四种

方法；然后具体实现基于 PowerPC 平台的 VxWorks BSP，以及基于 ARM 平台的嵌入

式实时 Linux BSP，并给出测试结果；最后总结全文，指出进一步研究的方向。

本文介绍的 BSP 设计方法对优化和扩充 BSP 的基本功能有一定的指导意义。本文

实现的 VxWorks BSP 和嵌入式实时 Linux BSP，对嵌入式系统固件的开发与优化有着

重要的参考价值-Embedded real-time operating system and BSP introduces the function and module division, based on the analysis of BSP in this process and the typical structure of the main frame　then introduces and analyzes the design of embedded real time operating system BSP four methods　and concrete implementation platform based on PowerPC The VxWorks BSP, as well as ARM-based platform for embedded real-time Linux BSP, and gives test results　final concluding remarks, pointed out that the direction of further study. This article describes the design method BSP BSP optimization and expansion of the basic functions of a certain significance. This realization of the VxWorks BSP and embedded real-time Linux BSP, embedded systems firmware development and optimization has important reference value
