FPGA accelerator card resetting method and device and FPGA accelerator card

The invention discloses a method for resetting an FPGA accelerator card. The method comprises the following steps: collecting configuration information of each processor; when a first reset request sent by a first processor is received, determining a first target device corresponding to the first reset request in the FPGA accelerator card, and processing the first reset request according to firstconfiguration information of the first processor; and sending the processed first reset request to the first target device to enable the first target device to execute the first reset request. According to the technical scheme provided by the invention, the whole reset process is independent of the development of related applications of the FPGA accelerator card, and the reset sequence among multiple processors does not need to be controlled through an upper-layer application, so that the applications do not need to be configured and modified, and the development cycle and cost of the applications are reduced.
