Abstract

The invention provides a memory management method and a memory management device. wherein the method and teh device are used for executing memory allocation and / or memory de-allocation by using a plurality of independent idle linked lists; wherein the plurality of independent idle linked lists provide information of a plurality of memory blocks, the memory allocation and / or the memory deallocationare / is executed according to the states of the memory blocks, and the states of the memory blocks comprise a use state which indicates that the memory blocks in the use state are being used and cannot be used for allocation; The link state indicates that the memory block in the link state is not used, is linked in one idle linked list of the plurality of independent idle linked lists, and can beused for distribution; And an idle state indicating that the memory block in the idle state is not used, and is not linked within any one idle linked list of the plurality of independent idle linked lists, and is not available for allocation.

Description

technical field [0001] The present invention provides a memory management method and device for performing memory allocation and / or memory deallocation by using multiple independent free linked lists. Furthermore, the invention relates to a correspondingly arranged computer program product and a correspondingly arranged computer readable medium. Background technique [0002] Memory management is essential in all computing systems and devices. Memory resources are required to perform computations on a computing system or device and to process data in a computing system or device. Memory resource management is usually implemented by a memory allocator. A typical memory allocator is a single memory accounting facility with an efficient interface for allocating and deallocating memory blocks of the required size. In a computing system or device, the memory allocator is requested to provide a block of a certain size for executing one or more processes and / or storing data in th...
