Memory allocation method and apparatus of financial terminal

Abstract

The invention discloses a memory allocation method of a financial terminal. A memory of the financial terminal comprises an occupied space and a continuous idle space, the occupied space and the continuous idle space separately comprise preset node spaces, the continuous idle space further comprises an address of a next space starting position, a space state and the address of a previous space starting position, and the method comprises the following steps: receiving a memory application instruction sent by an external device; searching the continuous idle space that can satisfy the demand of the memory application according to information in the memory application instruction and the preset node spaces; and if the continuous idle space that can satisfy the demand of the memory application is searched, allocating a corresponding space in the continuous idle space according to the memory application instruction, and modifying the address of the next space starting position and the space state in the preset node space of the continuous idle space. The invention further discloses a memory allocation apparatus of the financial terminal. By adoption of the memory allocation method and apparatus provided by the invention, the utilization rate of the memory space can be improved, and the data processing speed can be improved.

Description

technical field [0001] The invention relates to the field of computer science and technology, in particular to a memory allocation method and device for a financial terminal. Background technique [0002] At present, financial terminals generally interact with the platform, so the processing of financial terminal data also needs to interact with platform data, but when data interaction occurs between the platform and the terminal, the interactive data has no fixed length, and the scope of financial terminal data and platform data A big difference. When presetting the space on the financial terminal, the preset space needs to be set to a large size, which will increase the demand for memory. [0003] In order to reduce memory requirements, existing memory management technologies mostly use bit marks to indicate memory storage conditions. If the memory represented by a single bit mark is too small, too many mark bits need to be used, which will cause a waste of space, and wh...

AI Technical Summary

Problems solved by technology

If the memory represented by a single bit mark is too small, too many mark bits need to be used, which will cause a waste of space, and when the memory represented by a single bit mark is too large, the memory space utilization rate of a single application will be relatively low , at the same time, in the process of memory application and memory release, multiple displacement calculations and multiple bit-and operations need to be performed, which takes a long time, so when using bit marks to indicate the storage status of the memory, the utilization rate of the memory space will be relatively low , and the data processing rate will be slower
