Abstract

The invention discloses a memory allocation method, a memory allocation device and a memory recovery method. The memory allocation method comprises the following steps: comparing a system allocation parameter with required capacity in an obtained memory allocation request; if the required capacity is less than or equal to the system allocation parameter, allocating a first type of memory, and setting a using state for the first type of memory which is allocated, wherein the capacity of the first type of memory is preset, and is matched with the required capacity in the memory allocation request; and if the required capacity is greater than the system allocation parameter, allocating a second type of memory with the required capacity, and setting a using state for the second type of memory which is allocated. According to the technical scheme, memory fragments are reduced, and the working efficiency of a system and the performance of the memory are improved.

Description

Technical field [0001] The invention relates to the technical field of memory allocation, in particular to a memory allocation method and device, and a memory recovery method. Background technique [0002] The memory is a channel connecting the CPU and other devices, playing the role of buffering and data exchange. When the CPU is working (for example, the CPU runs a program), it needs to read data from external storage such as hard disks, but because the hard disk "warehouse" is too large and it is also far from the CPU, the speed of transporting "raw material" data It is relatively slow, resulting in greatly reduced CPU production efficiency. In order to solve this problem, a "small warehouse"-memory was built between the CPU and external storage. [0003] The current memory allocation and recovery mechanism is usually: each time a program running by the CPU needs to use memory, it requests memory from the system (can be called a memory allocation request), and the system runs ...
