Problems solved by technology

During the typesetting process, as the context changes, these types of rectangular data structures will be frequently allocated and released. For example, when inserting a picture into a web page, the web page will release and regenerate the rectangular data structure in a local area, from From a memory management perspective, this leads to frequent memory allocations and deallocations

Embodiment Construction

[0028] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0029] The present invention is an application-level memory management solution, which provides two sets of memory management mechanisms, which are:

[0030] Use pooled memory management (Pooled Memory Management) to manage the allocation and release of fixed-size data structures, and use the garbage collection mechanism to reclaim its memory fragments;

[0031] The vector method is used to manage the allocation and release of variable-sized data structures, such as strings, and the compression mechanism is used to reclaim its memory fragments.

[0032] Describe in detail below in conjunction with specific embodiment:

[0033] Application browser memory management is a method of reorganizing memory on an allocated memory, and it does not involve the memory management of the operating system.

Abstract

The invention discloses a memory management method at application program level, including the management of the memory space of a fixed-size data structure and a variable-size data structure. The management method comprises managing the allocation and the release of the memory space of the fixed-size data structure in a pool-type memory management mode, and recovering memory fragments generated during the allocation and the release processes of the memory space of the fixed-size data structure by using a garbage collection mechanism; managing the allocation and the release of the memory space of the variable-size data structure in a vector mode, and recovering memory fragments generated during the allocation and the release processes of the memory space of the fixed-size data structure by using a compression mechanism. The invention improves the management efficiency of the memory allocation and release without causing system to halt due to depletion of the system memory, and is more efficient than the memory management of a system.

Description

technical field [0001] The invention relates to memory management technology, in particular to an application-level memory management method. Background technique [0002] In an embedded system, since the total available memory is relatively small, the normal operation of the browser (browser) requires relatively large memory and frequent memory allocation and release. A text field, various forms (Form) and various pictures, etc., are represented by several rectangular data structures (box). During the typesetting process, as the context changes, these types of rectangular data structures will be frequently allocated and released. For example, when inserting a picture into a web page, the web page will release and regenerate the rectangular data structure in a local area, from From a memory management perspective, this leads to frequent memory allocations and deallocations. In order to ensure the normal operation of the browser and reduce internal fragmentation, it is nece...
