Abstract

The invention discloses an application memory management method and device, belonging to the technical field of communication. The method includes: after receiving the application memory request from the application, querying the memory application interface for operating memory paging; according to the size of the memory page provided by the memory application interface for operating memory paging, allocating a memory block for the application; A guard page is added to a start position or an end position of the memory block allocated by the application, and the guard page is used to provide exception detection for the debugger. The present invention directly takes over the memory application interface of memory paging, allocates memory blocks for applications according to the size of memory paging, and adds a protection page to one end of the memory block, which can detect illegal reading and writing of memory, and at the same time, the detection coverage rate is higher high.

Description

technical field

[0001] The present invention relates to the technical field of communication, in particular to an application memory management method and device. Background technique

[0002] The development of native applications on low-end mobile phone platforms (mobile phone Java applications do not belong) generally uses C language or C++ language, and the memory management mechanism provided by the platform is relatively primitive, which requires application developers to have good quality, otherwise it is easy to cause memory loss. Leakage or illegal memory access can slow down the running speed of the application or the system, or even crash the system.

[0003] In order to develop more stable native applications on these platforms, a current method of managing application memory is to take over the MMU (Memory Management Unit, memory management unit) at runtime. The way to take over the MMU at runtime is to build a memory management module by the application itself...
