Problems solved by technology

[0003] However, when the speed at which the message processing unit processes the data block is relatively slow, the release speed of the storage resource in the first storage unit is also relatively slow, but the queue management unit will still apply for a destination address from the MMU, and the DMA unit will transfer the second storage resource to the MMU. The data blocks in the unit are copied to the first storage unit, resulting in insufficient storage resources of the first storage unit, which becomes the bottleneck of the message transmission system

Abstract

Provided are a method and device for scheduling storage resources. The method comprises: counting a first data block stored in a first storage unit so as to obtain a counted value; according to the counted value and a preset counted threshold value, applying a destination address to an MMU so as to obtain the destination address; sending the destination address and a message transmission indication to a DMA unit so as to make the DMA unit extract a second data block from a second storage unit and storing the second data block in the first storage unit according to the destination address. The technical solution provided in the embodiments of the present invention is used to control the storage resources occupied by a data block and save storage resources.

Description

technical field [0001] The invention relates to computer technology, in particular to a storage resource scheduling method and equipment. Background technique [0002] At present, in the message transmission mechanism based on dynamic storage resource management, after receiving the message transmission instruction sent by the message processing unit, the queue management unit applies for the destination address from the memory management unit (MMU), and then transfers the applied destination address to and message transmission instructions are sent to the direct memory access (Direct Memory Access, DMA) unit, so that the DMA unit transfers the second storage unit, such as Double Data Rate Synchronous Dynamic Random Access Memory (DDRSDRAM) according to the destination address ) to the first storage unit, such as shared secondary (Share Level2, SL2) memory, and at the same time, the queue management unit writes the destination address into the receiving queue, so that the me...
