Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0037] The present invention is mainly aimed at providing a general solution for memory management when multiple modules need to frequently share data and have high performance requirements during the middleware development process, and provide a solution for middleware development. An efficient and stable way to access memory; and can complete the work of synchronizing data required for concurrent access to data, and provide an application programming interface to simplify the development of concurrent access to shared memory.

[0038] Therefore, in the structured area, it can be divided into different storage areas according to the size of the storage unit, and the size of the storage unit can also be increased sequentially according to the number of bytes such as 1k, 2k, 4k, etc. Each storage area has its own area header information to save the ...

Abstract

The invention relates to a memory management method in system development work. A middleware memory management method comprises the following steps of: starting a middleware application system, obtaining a memory area according to configuration, and initializing the memory area, namely, setting the memory area as a structured area and an expansion area, wherein the structured area is divided into a plurality of storage units with fixed capacity, structured area general head information is set, the expansion area is provided with expansion area general head information, and the expansion area general head information comprises an idle unit linked list and a used unit linked list; when some module applies for the memory, allocating the memory according to the applied requirement; allocating the memory to the specific storage unit in the memory area, and releasing the memory after being used by the storage unit; when the application system stops, clearing the content of the memory area. The scheme realizes efficiency and steady concurrent access to the memory, and provides a universal solution for the problem of memory management problem in the application system development process.

Description

technical field [0001] The invention relates to a memory management method in system development, in particular to a memory management method in product development, especially middleware development. Background technique [0002] Memory management is a problem that needs to be considered in many system development tasks. Efficient and stable memory management is a prerequisite for a reliable system operation. [0003] In the current implementation of the existing memory management system, the following aspects of memory management are mainly considered: [0004] 1. Establish the mapping relationship between the physical address of the memory and the logical address, maintain the physical page information of the memory, etc. This management system involves the hardware level and is mainly used for the development of embedded systems. [0005] 2. The protection measures for memory access mainly consider the measures that need to be taken when accessing memory out of bounds ...
