Abstract

The invention is suitable for the technical field of the computer, and provides a data acquisition method, device and terminal. The method comprises the following steps: receiving a data acquisition request sent by end-point equipment; suspending the forwarding of the data acquisition request if the data size for accomplishing data storage exceeds the preset threshold by the execution of the dataacquisition request; and forwarding the data acquisition request if the data size for accomplishing data storage cannot exceed the preset threshold by the execution of the data acquisition request. Through the method provided by the embodiment of the invention, the bandwidth of read request destination equipment of the computer in data processing cannot be reduced by excessive read request, the congestion is avoided, and the computer performance cannot be influenced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data acquisition method, device and terminal. Background technique [0002] In the computer architecture, there are many different computer I / O interconnection standards, the most popular of which are the Peripheral Component Interconnect (PCI) standard, the high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE) has become very popular as the next-generation bus of PCI. In a PCIE system, the root complex connects the processor and memory subsystems into a PCIE switch fabric consisting of one or more switch devices. The number of PCIE ports of the root complex may be more than one, and multiple switching devices may be connected to different PCIE ports of the root complex, or multiple switching devices may be connected to the root complex by cascading. PCIE also supports split read completion, which means that read request...
