摘　　要：本文以提高嵌入式计算机硬件兼容性、软件重用性及移植性为目的,对嵌入式计算机硬件抽象层与操作系统接口进行探索,提出了硬件抽象层的实现方法,通过改造VxWorks操作系统对隔离机制进行了验证,验证结果表明硬件抽象层的实现大大提高了嵌入式计算机的兼容性,同时对系统的性能影响极小。In order to improve the compatibility of the hardware and improve the reusability and portability of the software, We explored the Embedded Computer interface between hardware abstraction Layer and operating system, and also propose the implementation of the hardware abstraction Layer. The isolation mechanism has been verified by the alteration of the VxWorks operating system. It is proved that the implementation of hardware abstraction layer improve the compatibility of the embedded computer, while minimal impact on system performance,
