摘要
为提高嵌入式实时系统中处理器间通信效率,针对通常传输层协议的不足,设计并实现了嵌入式系统中RUDP通信模块,以实现嵌入式分布系统中各进程间可靠、高效的通信。首先给出了RUDP通信模块的基本功能、任务划分和控制机制;其次阐述了RUDP通信模块的实现过程,包括滑动窗口、消息和应答的识别与处理、主要定时器的处理和定时器管理;最后给出了结论。
In order to enhance the communication efficiency of embedded real-time systems, in allusion to the insufficiency of the general transport layer protocol, the RUDP communication module for embedded systems is designed and implemented, aiming at the implementation of reliable and efficiency communication between processes. Firstly, the base function, the task division and the control mechanism of RUDP communication module are given. Secondly, the implementation process of RUDP communication process is illustrated, including the slide window mechanism, the recognition and transaction of messages and responding, transaction of the main timer and the management of timers. The conclusion is given at last.
