High-speed internal memory application and release management system with controllable internal memory consumption and high-speed internal memory application release management method

Abstract

The invention discloses a high-speed internal memory application and release management system with controllable internal memory consumption, which is realized through mutual matching of an operating system, a page internal memory pool and idle internal memory chain tables, wherein the page internal memory pool comprises an internal memory page, a plurality of idle internal memory chain tables respectively manage idle internal memory chips with same bytes, and the page internal memory pool can provide an internal memory for the idle internal memory chain tables and can also receive the internal memory released by the idle internal memory chain tables. The invention also provides an internal memory management method realized by using the high-speed internal memory application and release management system. The internal memory application release management system and method can realize rapid application and release of the internal memory, and can effectively control internal memory footprint. When the internal memory is applied and released, caches are provided for the former layer of internal memory through the page internal memory pool without calling an internal memory management interface of the operating system, thus the application and release speeds of the internal memory are increased, meanwhile, through setting upper limits for the capacity of the page internal memory pool, the internal memory footprint of the whole application system is further controlled, and the internal memory utilization rate is increased.

Description

technical field [0001] The present invention relates to a memory management system, in particular to a high-speed memory application release management system suitable for databases, industrial control fields and embedded systems with controllable memory consumption; Methods of application and release. Background technique [0002] In the field of industrial control and embedded applications, the real-time requirements of the system are usually very high. Since the memory resources of the system are relatively limited, when the application software occupies too much memory, the real-time performance of the system will be reduced, which may affect the entire system. Therefore, in order to ensure the real-time performance of the system, the memory usage of the application system must be controlled, and the memory must be quickly applied and released. [0003] The memory management function of ordinary operating systems is open to users through API interfaces (such as malloc a...

Problems solved by technology

This method can improve the utilization rate of memory by adjusting different types of memory. However, since it applies for small memory, it essentially applies to other small memory. Therefore, the CPU overhead of memory management is relatively high, and small memory release , the released memory will not be returned to the operating system. Therefore, the total amount of memory in the entire system can only increase, not decrease. After the memory usage reaches its peak value, the memory usage will not fall back.
