Chip, IO scheduling method and IO scheduling device

Abstract

The invention provides a chip, an IO scheduling method and an IO scheduling device. The chip comprises a processor, a first-in-first-out queue and a controller, wherein the processor is used for executing IO commands, the chip comprises the first-in-first-out queue in communication connection with a register and the processor, the first-in-first-out queue is used for storing timeout commands and sending the timeout commands to the processor according to the storage sequence, the timeout command is an IO command of which the time delay exceeds the command timeout time of the IO command, and the command timeout time is set according to priority of the IO command; and the controller is used for monitoring the time delay of the IO command and pushing the IO command to a first-in first-out queue under the condition that the time delay of the IO command is greater than the command timeout time of the IO command, and the processor is used for executing the IO command. The chip solves a problem of high IO command delay of an IO scheduling algorithm in the prior art.

Description

technical field [0001] The present application relates to the field of chip technology, and in particular, to a chip, an IO scheduling method, an IO scheduling device, a computer-readable storage medium, and a processor. Background technique [0002] Existing IO scheduling algorithms are all implemented based on software, and IO scheduling is processed on the device side. Based on the embedded operating system, it is relatively difficult to debug and track. On-chip IO scheduling is caused by unbalanced and unreasonable internal IO processing. IO latency is high. [0003] The above information disclosed in the Background section is only to enhance the understanding of the background of the technology described herein, therefore, the Background may contain certain information which is not formed in the country for those skilled in the art. known prior art. Contents of the invention [0004] The main purpose of the present application is to provide a chip, an IO scheduling ...
