Abstract

The invention provides a plug-in loading method and device for PCI-E (Peripheral Component Interconnect-Express) equipment, and relates to the technical field of PCI-E bus interfaces. The method comprises the steps of acquiring a user plug-in of host equipment, and storing the user plug-in into a PCI BAR shared memory; reading the user plug-in in the PCI BAR shared memory, and generating a shared library file in a PCI-E file system according to the user plug-in; dynamically loading the shared library file via a dynamic link library in the PCI-E equipment, and running the user plug-in. By adopting the method and the device, the PCI-E equipment can load the user-defined user plug-in, and the problem that the user plug-in program defined and edited by a user cannot be loaded to the PCI-E equipment at present so that the function of the PCI-E equipment is single is solved.

Description

technical field [0001] The invention relates to the technical field of PCI-E bus interface, in particular to a plug-in loading method and device for PCI-E equipment. Background technique [0002] At present, the new generation of bus interface (PCI-Express, referred to as PCI-E) adopts the current popular point-to-point serial connection. Compared with the shared parallel architecture of the PCI bus and earlier computer buses, each device has its own dedicated Connection does not need to request bandwidth from the entire bus, and can increase the data transfer rate to a very high frequency, reaching the high bandwidth that PCI cannot provide. In the protocol specification of PCI-Express v3.0 version, a single-channel PCI-E bus can reach a theoretical bandwidth of 8Gbp / s, and a 16-channel PCI-E bus can reach a theoretical bandwidth of 128Gbps. In addition, PCI-E also has the characteristics of convenient host access. Computer peripherals connected by PCI-E bus and host (gen...
