摘要： 针对嵌入式异构计算系统中计算单元间的互联需求，面向CPU及FPGA平台设计一种工作在发布-订阅模式下的消息中间件。首先研究发布-订阅模型及对应的报文传输方式，为解决可靠组播的错误控制、拥塞控制问题选用RapidIO作为中间件传输协议。其次研究中间件的通信方案与发布-订阅机制的实现方案并设计了热插拔机制与异常监测模块以提升可靠性。系统验证与测试结果表明，中间件具有较好的通信性能，且热插拔机制有效提升了系统的可靠性，与其他设计方案相比具有一定优势。

Design of MOM for heterogeneous platforms based on publish-subscribe mechanisms

Abstract： Aiming at the interconnection demand between computing units in embedded heterogeneous computing systems, a message middleware working in publish-subscribe mode is designed for CPU and FPGA platforms. Firstly, we study the publish-subscribe model and the corresponding message transmission method and choose RapidIO as the middleware transmission protocol to solve reliable multicast error control and congestion control problems. Secondly, we study the middleware's communication scheme and the publish-subscribe mechanism's implementation scheme and design the hot-plugging mechanism and the anomaly monitoring module to improve reliability. System validation and testing results show that the middleware has better communication performance, and the hot-plugging mechanism effectively enhances the system's reliability, which has certain advantages compared with other design solutions.
