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...
