Problems solved by technology

If you still adopt the method of dynamic memory allocation during system initialization, you can only create a memory pool according to the minimum available memory to prevent memory leaks and other problems, and this method is obviously unreasonable for embedded systems with relatively tight memory resources. of

Abstract

The invention discloses a memory management method which comprises the following steps of predefining a public code and a private code; dividing memory space with preset size to the public code; selecting the private code according to actual scene; dividing corresponding memory space according to the selected private code to load the private code; and establishing a memory pool according to the rest available memory. Compared with the prior art, the establishing time of the memory pool of the memory management method provided by the invention is in the stage after program codes for specific operation of systems are determined, instead of the initialization stage of the systems so that when the memory pool is established, the rest available memory of the systems is known and is capable of maximizing the available space for establishing the memory pool, and thus, the use efficiency of memory is greatly improved.

Description

【Technical field】 [0001] The invention relates to memory management of an embedded system, in particular to a method for dynamically creating a memory pool. 【Background technique】 [0002] In the use of resources in embedded systems, memory resources are usually relatively tight. At present, most embedded systems use dynamic allocation of memory. When applications need to use memory resources, they apply for them and release memory resources after use. In embedded systems with traditional architecture, especially in real-time operating systems (RTOS), the dynamic allocation of system memory is done in the system initialization stage, and is not done during the entire program running cycle. Modified way. Since the embedded system of the traditional architecture can determine the size of the remaining available memory after initialization in the system initialization stage, there is no problem in this way. [0003] However, for embedded systems with new architectures using c...
