中文摘要: 近年来,随着嵌入式计算机技术飞速发展,各种异构嵌入式硬件不断更新,提高操作系统的可移植性和应用程序的代码重用性成为了一种趋势.本文设计了一种通用性较强的平台抽象层,针对Linux操作系统、“锐华”操作系统与硬件平台的应用程序开发接口重新进行设计,为用户开发各种嵌入式应用程序提供标准化的接口.研究证明,平台抽象层能提高操作系统的可移植性和应用程序的代码重用性,同时具有可靠的实时性.
Abstract:In recent years, with the development of embedded computers as well as the appearance of various kinds of heterogeneous embedded hardware, it is a trend to improve the portability of operating systems and the code reusability of application programs. In this paper, we introduce a platform abstraction layer with strong universality, which is designed for Linux and ReWorks operating systems and hardware platforms. Specially, the platform abstraction layer redesigns the application programming interface to provide a unified interface to users to develop various embedded applications. It is proved that the platform abstraction layer can improve the portability of operating systems and the code reusability of application programs. At the same time, it has reliability in terms of real-time performance.
