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

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.
