Abstract

The invention discloses IO request pipeline processing equipment. The equipment mainly comprises an IO state buffer and a pipeline controller, wherein the IO state buffer comprises a plurality of elements and is used for storing context information comprising a module calling sequence generated by the CPU; and the pipeline controller is used for carrying out pipeline control on the IO request according to the context information. According to the equipment, assembly line management of an IO processing state is carried out through the arrangement of a hardware module, the huge workload of an original CPU software control process is shared, the requirement for CPU design is reduced, meanwhile, triggering of processing logic of the assembly line controller is achieved through the module calling sequence recorded in the IO state buffer, the implementation power consumption can be reduced, and the implementation efficiency can be improved. Correspondingly, the invention further provides a method and system corresponding to the IO request pipeline processing equipment and a readable storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The present invention relates to the technical field of request processing, in particular to an IO request pipeline processing device, method, system and readable storage medium. Background technique [0002] A solid-state drive (SSD) is a device used to store user data. Solid state hard drives are composed of modules such as controllers and storage media NAND (flash memory). The solid-state hard disk communicates with the host, and the host sends storage requests to the solid-state hard disk, and notifies the solid-state hard disk of the data to be stored. After obtaining the request, the SSD stores the data in the NAND (flash memory) medium. [0003] One reason why solid-state drives have extremely high performance is that they provide high concurrency, that is, the host can send multiple requests to solid-state drives, and solid-state drives can process the next request at the same time before a request is processed. This concurrency is typically...
