Abstract

The invention provides a memory management method and system. The method comprises the following steps: the system dividing a to-be-processed statement into a plurality of sub-statements step by step according to an order from high to low of processing order priorities of processing identifications in the to-be-processed statement, wherein the processing identification is used for identifying a logic processing relationship between the sub-statements in the same level; saving the each level of divided sub-statement containing the processing identification in a plurality of memory segments according to the priorities; determining the highest priority as the current priority according to the order from high to low of the processing order priorities of the processing identifications; reading the sub-statement from the memory segment corresponding to the current priority, processing the statement to obtain a processing result, and saving the processing result in the memory segment corresponding to the next priority; releasing the memory segment corresponding to the current priority, and updating the next priority as the current priority, and returning to an operation of reading or processing the sub-statement until the processing of the to-be-processed statement is finished. The method and system provided by the invention can improve the memory usage efficiency.

Description

technical field [0001] The invention relates to the field of computer processing, in particular to a memory management method and system. Background technique [0002] Memory management has a crucial impact on a large-scale system. Occupying a large amount of memory and frequent memory applications will increase the burden on the system, which will eventually lead to a decrease in the operating efficiency of the system. [0003] The existing basic principle of memory management is: reduce the number of memory allocations to the operating system, that is, apply for multiple uses once. The general way is to allocate a large memory to the operating system at one time, and prepare two linked lists; divide this large memory into multiple small memory blocks, and add all small memory blocks to the free linked list, and remove them from the free linked list when the system uses them. , put it into the working linked list, and put it back into the free linked list after use; when o...
