Buffer resource allocation method, module and electronic equipment

Abstract

The embodiment of the invention provides a buffer resource allocation method and module and electronic equipment, and relates to the field of storage management. Modules may be disposed in an electronic device to implement the method. The method comprises the following steps: receiving a resource occupation request carrying a request buffer length, determining an allocation resource segment of which the total length is greater than or equal to the request buffer length from a plurality of buffer resource segments according to the resource occupation request, then allocating the allocation resource segment to a request resource, and marking an identification number corresponding to the allocation resource segment as an occupation state. When a resource occupation request exists; determininga plurality of distribution identification numbers from the plurality of available identification numbers, and the total length of the distributed resource segments corresponding to the distributed identification numbers is greater than or equal to the request buffer length, and then the buffer resource segments corresponding to the distributed identification numbers are distributed to the request resources corresponding to the resource occupation request, so that the problem of low read-write efficiency of the storage medium is solved.

Description

Technical field [0001] The invention relates to the field of storage management, and in particular to a buffer resource allocation method, module and electronic equipment. Background technique [0002] In storage media, there are usually multiple resource request modules that perform data read and write operations at the same time. For write data operations, the resource request module first writes the write data to the buffer resource of the buffer resource allocation module, and then reads and writes data from the buffer resource. The write data is read from the resource and written to the storage unit. For read data operation, the resource request module first stores the read data from the storage unit into the buffer resource, and then sends the read data from the buffer resource. [0003] Currently, the buffer resource allocation method has the problem of low read and write efficiency of storage media. Summary of the invention [0004] The purpose of the embodiments of the pr...
