硕士论文-分布式信息化平台中嵌入式实时中间件研究，正文共63页。
【摘要】 随着信息化时代的到来,军事、航天、工业控制领域对中间件的要求越来越高,实时中间件逐渐成为实现分布计算的关键技术之一。实时中间件提供了真正的通用软件总线结构,可以去掉当前分布式实时系统的不灵活结构,中间件与实时系统的结合成为今后分布式实时系统的一个重要发展方向。本文对实时中间件进行了全面的研究。首先,介绍了实时系统的概念、特点、结构、调度和实时支撑平台。然后,讨论了中间件的概念、分类、实时应用对中间件的要求、实时中间件研究的主要问题、实时中间件的设计原则和实时中间件的体系结构。最后,本文根据实时CORBA规范,分析了实时中间件的实现,包括优先级映射方法、处理器资源管理、存储器资源管理和网络通信资源管理。对实时中间件主要功能模块进行了实现并予以验证。
【Abstract】 With the advent of the information age, demands for the middleware in military, aerospace and industrial control field are increasing day afer day. Real-time middleware has become one of the key techniques in distributed computing implementation.Real-time middleware offers a common soft bus framework eliminated distributed real-time systems unhandy architecture. So, middleware integrated with real-time system becomes an important developmental direction.In this thesis, real-time middleware has been studied in the round. First, this thesis introduces concept, characteristic, architecture, scheduling of real-time systems and real-time infrastructure. Then this thesis discusses concept, classify of middleware, real-time application request to middleware, the problems that real-time middleware is faced with at present, design principle of real-time middleware, and architecture of real-time middleware.According to real-time CORBA specification, this thesis discusses implementation of real-time middleware. They are real-time CORBA priority mapping methods, real-time CORBA processor resource management, real-time CORBA memory resource management and real-time CORBA communication resource management. Finally, this thesis achieves and verifies the main function modules of real-time middleware.
