Memory allocation processing method and device

Abstract

The embodiment of the application discloses a memory allocation processing method and device. The method comprises the steps that memory application information is obtained, and whether or not the applied memory is less than the maximum allocable memory of the memory blocks in the established memory pool is judged; when it is determined that the memory application is greater than the maximum allocable memory, according to the recorded large block of memory information in the data header of the memory block, the memory is allocated from the large block of memory to the application memory; otherwise, whether or not the application memory is greater than the free memory of current memory block is judged, when it is determined that the application memory is less than the free memory of current memory block, whether or not the current remaining space of current memory block meets the needs for the application memory is judged; if the current remaining space of current memory block meets the demand by the application memory, the memory is allocated from the current remaining space of current block memory block to the application memory. By the method and device, the time spent for memory allocation can be reduced, the memory utilization rate of a system is increased, and memory allocation efficiency of the system is optimized.

Description

technical field [0001] The present application relates to the technical field of memory management, in particular to a memory allocation processing method and device. Background technique [0002] With the development of communication technology, people can realize the interactive transmission of data and information by establishing a network connection between the terminal and the server. Not only that, different terminals can also use the data transmission method for interactive communication, and people can obtain the required information through the Internet established by the above transmission method. [0003] Usually, in the Internet, when the communication parties have data interaction, a connection needs to be established, and after the data transmission is completed, the connection is disconnected, that is, each connection only completes the sending of one service, such a connection is called short connection. However, as far as different terminals are concerned,...

Problems solved by technology

However, in the above memory allocation method, it is easy to generate memory fragments in the allocated free memory blocks, and the memory utilization rate is not high. Moreover, due to the frequent allocation of memory during the long connection communication process, the physical addresses of the free memory blocks are different. Continuous, the server needs to spend more time searching for available free memory blocks during the calling process, and the efficiency of memory allocation is not high

[0005] In the memory allocation processing method of long-connection communication in the prior art, when there are a large number of connection requests, the server needs to continuously consume resources for calculation, and it takes a lot of time to search for available free memory blocks, and it is easy to find in the allocated free memory blocks. Generate memory fragmentation, resulting in low server system memory utilization and low memory allocation efficiency
