摘要
本文结合一个具体的嵌入式系统的实现 ,探讨了硬件抽象层 HAL( Hard-ware Abstraction Layer)的作用、主要内容以及具体实现方式等 。
In this paper,HAL Hardware abstraction layer),especially its functions,essentialities and realization,is discussed in detail,based on implementation of a specific embedded OS (operating system).The principle and fundamental method for the realization of HAL are put forward as well.
