Abstract: With the development of software radio, software satellite and other technologies, middleware as a software platform supporting technology has been extensively studied. The current middleware types mainly include object-oriented component type and message middleware, but most middleware, such as Kafka, RocketMQ, etc., are oriented to PC platform applications and cannot be adapted to embedded platforms. At the same time, its design pays too much attention to high concurrency and high performance, which cannot meet the real-time and high reliability requirements of military electronic systems. In order to meet such applications, OMG proposed a data-centric publish/subscribe communication model to provide data distribution services, and released relevant specifications. In this paper, the micro xrce-dds (extreme resource constrained environment data distribution service) middleware is deployed on the CPU, FPGA, DSP and other embedded processors to realize the publish and subscribe of different topic data based on the middleware in the embedded heterogeneous platform.
