AI Technical Summary
In communication between hybrid real-time operating systems and non-real-time operating systems, there is a communication latency problem caused by cross-NUMA access due to the non-real-time operating system reserving memory for the RTOS.
By identifying the target NUMA node from among the alternative non-uniform memory access NUMA nodes and utilizing the processor corresponding to that node to perform data communication, threads and processors are bound together to optimize the communication path and improve data transmission efficiency.
It reduces communication latency between operating systems, improves the speed and real-time performance of data communication, fully leverages the advantages of NUMA architecture, and reduces cross-node access latency.
