MCU end DDS communication method and device and computer equipment

Abstract

The embodiment of the application relates to the technical field of automatic driving communication, and discloses an MCU end DDS communication method, device and computer equipment, the method is realized based on an MCU end DDS communication device, the device at least includes a first core, a second core and a cross-core shared memory, the first core deploys a DCPS core component, the second core deploys an RTPS core component, and the DCPS core component and the RTPS core component realize data transmission through the cross-core shared memory.The application separates and deploys the DCPS core component and the RTPS core component in the dual core, realizes efficient data interaction through the cross-core shared memory, the dual-core separation deployment enables the parallel execution of the calculation-intensive task and the I / O-intensive task, so that the parallel processing capacity of the multi-core MCU is fully released, single-core resource preemption is avoided, and the waste of computing power is reduced; the asynchronous sending mechanism is adopted to reduce the communication delay and jitter, and the priority of key services is guaranteed; and the dual-core parallel processing improves the data transmission throughput, and simultaneously enhances the system running stability.
