Problems solved by technology

[0003] In the long-term research and development process, the inventor of the present invention found that the current operating system uses a single way of using reserved memory. When the operating system allocates a section of reserved memory for a component / application program, there is no second A component / application can use this block of memory, resulting in a waste of memory resources, but also reduces the size of the running memory and increases the probability of errors due to insufficient memory

Embodiment Construction

[0014] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0015] The invention provides a memory management method, which is at least applied to the management of the memory by operating systems of vehicles, computers, and mobile devices. In the operating system, the available physical memory is fixed and determined by the actual physical device of the memory. If the physical device is not replaced, the available physical memory will not change. For example, a 1G memory stick (Random-Access Memory, RAM) means that the physical memory has 1G, and this value will not change.

[0016] When running the operating system, the operating system divides the physical memory into two parts, the running memory and the reserved memory. Among them, the reserved memory is the space reserved by the operating syst...

Abstract

The invention discloses a memory management method, an electronic device and a device with a storage function, and the method comprises the steps: obtaining a currently required reserved memory valueof a component / application program, the reserved memory being a part of physical memory which is reserved for the component / application program by an operating system and cannot be mapped into a running memory; judging whether the currently required reserved memory value is smaller than an allocated reserved memory value or not, wherein the allocated reserved memory value is the size of a reservedmemory allocated to the component / application program by the operating system; and if the value of the reserved memory is smaller than the value of the allocated reserved memory, recovering the redundant reserved memory, and using the recovered reserved memory as an operation memory for reallocation. In this way, the memory utilization rate can be increased.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a memory management method, electronic equipment and a device with a storage function. Background technique [0002] As the core software of the device, the operating system manages the hardware and software resources of the device and maintains them in a normal state. In the hardware physical resources managed by the operating system, memory is an indispensable and important part. Currently, the memory viewed in the operating system is the total memory available when the operating system runs programs, that is, the running memory. This value is smaller than the actual physical memory that the operating system can use. For example, 1G of physical memory is the running memory viewed by the operating system. It is 0.9G. The 0.1G memory is the reserved memory (reserve memory) defined by the operating system. The reserved memory is a continuous memory area written in the DTS (Devi...
