Abstract

The invention discloses a memory management method and a memory management system, relating to the technical filed of information. The method is as follows: dividing a memory into a first memory area and a second memory area; using a local compression algorithm to manage the first memory area; and when the first memory area is in an unstable state, using the data stored in a second memory block to fill a hole causing the first memory area to be unstable, wherein the second memory block is positioned in the second memory area. The system comprises a division module, a management module and a filling module. A filling mode is used to greatly reduce the movement quantity of the memory to enable the memory to recover to a stable state, further improving the memory management performance of the local compression algorithm under the condition of ensuring higher use ratio of the memory, thereby ensuring that the local compression algorithm can better consider both the memory use ratio and the memory management performance.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a memory management method and a memory management system. Background technique [0002] Various protocols and algorithms running on the network are becoming more and more abundant, all of which need to configure and manage a large amount of memory to support them. There are two important parameters in memory management, namely, memory utilization and memory management performance. Memory utilization refers to The proportion of the space used by the memory. The memory management performance refers to the performance of applying for memory or releasing memory. The higher the memory utilization rate, the more memory needs to be moved to apply for memory or release memory, that is, the lower the memory management performance will be. Therefore, to achieve high memory utilization, the memory management performance will inevitably be reduced. [0003] Among the many memory manag...
