Method and device for managing off-chip memory, and computer-readable storage medium

Abstract

The invention discloses a management method and device of an off-chip memory, and a computer-readable storage medium, comprising: dividing the off-chip memory according to the storage capacity and storage bandwidth of the off-chip memory and the storage capacity and storage bandwidth required by each user program Create several storage spaces corresponding to each user program, and allocate several storage spaces to each user program; configure the read-write side scheduling strategy; receive write or read commands from user programs, and read and write according to the configuration The side scheduling policy and the allocated storage space schedule the data packets of the user program, write the data packets of the user program into the corresponding storage space or read the data packets from the corresponding storage space. The invention effectively ensures the storage space and storage bandwidth utilization rate of the off-chip memory, and reduces the use cost of the off-chip memory.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for managing an off-chip memory, and a computer-readable storage medium. Background technique [0002] With the rapid development of the Internet, people continue to put forward new service requirements for the network, and the limited on-chip memory resources cannot meet the increasing needs of user programs. At present, network service providers tend to use large-capacity off-chip memory to store messages and data, and double-rate (Double Data Rate SDRAM, DDR SDRAM) memory is used as the main off-chip memory, which is a high-performance, low-cost storage The solution has been widely used in PC (Personal Computer), server and today's system on chip (System On Chip, SOC) design. [0003] In the use of existing off-chip storage devices, usually as many groups of storage devices are used as there are sources. However, the capacity of the off-chi...

Problems solved by technology

However, for off-chip memory, storage bandwidth utilization is a very important factor. Using traditional cache management methods will cause waste of storage bandwidth and increase design costs.
