Abstract

The invention discloses a method and device for optimizing a memory of an audio and video codec and a storage medium, and relates to the technical field of memory optimization. The method comprises the following steps: according to the life cycle of each variable in an audio and video codec, dividing the variables with no intersection in the life cycle into one group; in any two groups, determining whether an intersection exists between the life cycles of the first maximum variable corresponding to the smaller group and the second maximum variable corresponding to the larger group or not; if the intersection does not exist, merging the smaller group into the larger group, wherein in the smaller group, the sum of the byte number occupied by the first maximum variable and the byte number occupied by the third variable is smaller than or equal to the byte number occupied by the second maximum variable; and according to the final grouping result, allocating the corresponding same memory unit to the variables in each group. By analyzing the life cycle of each variable in the audio and video codec, each variable is grouped to share the same memory unit, so that the consumption of the memory is reduced, and the optimization of the memory of the established audio and video codec is realized.

Description

technical field [0001] The present application relates to the technical field of memory optimization, in particular to a method, device and storage medium for optimizing the memory of an audio and video codec. Background technique [0002] There are two existing memory allocation methods: 1. Use the dynamic memory allocation method. When a continuous memory block needs to be used, a continuous memory block is allocated to it; Block release, this (NEW / FREE method) or (Malloc / Free method) dynamic memory allocation method will get the lowest memory usage, each data unit is allocated according to its complete life cycle, that is, when it starts to be used, and ends Release when used. 2. Use the static memory allocation method. During initialization, a fixed-size memory is allocated and divided into two types: (1) It is a globally fixed and independently used memory area. Each variable occupies a fixed position by itself and does not need to be linked with Other variable sharin...
