Problems solved by technology

Moreover, the memory space of the first type of memory management system and the second type of memory management system are independent, which will bring memory waste to the system as a whole. The existing memory management method needs to be transplanted and modified as a whole during development, and the development volume is large and difficult. , only a separate system can allocate and release its own memory. Since the program is in different stages, it cannot allocate memory or occupy too much memory and cannot be released.
[0003] It can be seen that the existing memory management methods have problems of poor management efficiency and adaptability

Abstract

Embodiments of the present disclosure provide a memory management method, device, and electronic equipment, which belong to the technical field of data processing. The method includes: when a memory allocation request is received, acquiring the current state type of the target program, where the state type is any one of interrupt context or task context; judging whether the current state type of the target program is an interrupt context; If the current state type of the target program is an interrupt context, allocate the memory of the interrupt area for the target program; if the current state type of the target program is a task context, first release the delayed release list memory address corresponding to the memory address, and then allocate memory in the task area for the target program. Through the processing scheme of the present disclosure, the system memory space is divided into an interrupt area and a task area, and memory spaces in different areas are correspondingly allocated to target programs of different state types, thereby improving the management efficiency and adaptability of the memory management system.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a memory management method, device and electronic equipment. Background technique [0002] At present, in small embedded devices, most of the real-time systems are used for memory management optimization. For some specific chips, two memory management systems are used simultaneously. The first type of memory system can be used in Allocate and release memory in task context and interrupt context; while the second type of memory system can only allocate and release memory in task context. Moreover, the memory space of the first type of memory management system and the second type of memory management system are independent, which will bring memory waste to the system as a whole. The existing memory management method needs to be transplanted and modified as a whole during development, and the development volume is large and difficult. , can only be allocated an...
