Global memory sharing method, global memory sharing device and communication system

Abstract

An embodiment of the invention provides a global memory sharing method, a global memory sharing device and a communication system to improve independence of sub-operation systems and reduce the pressure of a global memory management service. The method includes the steps: counting the page swap-out rate in the rotation period of tasks in predetermined times and the memory residence time ratio in the page swapping period by the sub-operation systems; calculating memory pressure indexes according to the page swap-out rate and the memory residence time ratio by the sub-operation systems; issuing application to the global memory management service by the sub-operation systems if the memory pressure indexes are larger than a memory pressure threshold. Under the architecture of a multi-operation system, the sub-operation systems can finish more adaptive work, global memory management service complexity is reduced, and system performances are improved. Besides, as the sub-operation systems can independently apply for and release memories, the utilization rate of a global memory can be increased, and the architecture of the multi-operation system has better expandability.

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...

AI Technical Summary

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
