硬件控制规范化访问API的一种实现方法

The Implementation of Formal API for Reference to Hardware

在仿真等工程实践中,硬件与软件的接口问题尚未规范化,对大型工程而言,由此产生的硬件驱动程序开发和应用程序开发之间的关联依赖、相似任务的重复开发、软硬件集成时的接口处理等问题,都对工程开发效率产生影响.针对此问题,定义了一个规范的硬件控制量的标识和访问方法,并采用DLL共享技术设计实现了一个支持该访问方法的通用服务软件接口系统,该系统具有通用性,实现了硬件驱动程序和应用程序的多节点部署、并行开发、无缝集成和网络通信的透明性,增强了软件的可重用性.

In project practices, a formal mode about the interface between hardware driving program and application program has not been bring ont. For large projects, this will bring to the dependence between developing of hardware driving program and application program, repeatedly developing on some work, the troubles in integration process, etc. These problems will reduce the developing efficiency. To avoid these, this paper defines a formal mode to identify and access hardware controlled items that are implemented as general software interface of service system with DLL shared technolo~. With hardware driving programs and application programs, the system is general and implements the multi -node deployment, concurrently developing, seamless integration, transparence to network communication and software reuse.
