Problems solved by technology
[0006] The defects of the existing multi-operating system structure using the global memory sharing method are: each sub-operating system lacks the ability of active memory awareness, and all global memory management tasks are handled by the global memory management service, resulting in global memory management coding. Complicated, low execution efficiency, and also affects the performance of the entire system

The embodiments of the present invention provide a global memory sharing method, device and a communication system, so as to improve the autonomy of the sub-operating system and reduce the pressure of the global memory management service. The method includes: the sub-operating system counts the ratio of the page swap rate during the predetermined number of task rotations and the memory resident time during the paging period; the sub-operating system calculates memory A pressure indicator; if the memory pressure indicator is greater than the memory pressure threshold, the sub-operating system sends an application to the global memory management service. In the method provided by the embodiment of the present invention, under the architecture of multiple operating systems, each sub-operating system can complete more adaptive tasks, reduce the complexity of global memory management services, and improve system performance. At the same time, since the sub-operating systems can be independently The application and release of memory can be completed in a timely manner, which can improve the utilization rate of global memory and make the multi-operating system architecture have better scalability.
Description
technical field [0001] The present invention relates to the communication field, in particular to a global memory sharing method, device and a communication system. Background technique [0002] With the further increase in data volume and data processing requirements, the load has higher and higher requirements on the performance of the operating system. Microkernel and multi-kernel have become a trend in the future development of the operating system. Multi-core cooperative work can well isolate applications, improve system throughput and greatly improve system performance. Therefore, in the face of big data processing today, various multi-core systems (or multi-operating systems) have gradually entered people's sight, from the traditional computer cluster system to the popular heterogeneous operating system. aspects of the attempt. [0003] The main idea of the multi-operating system structure is that different loads can be distributed to different operating system ke...
