Firmware updating method, device and medium of FPGA accelerator card

Abstract

The invention discloses a firmware updating method, device and medium of an FPGA accelerator card. The method comprises the steps that a configuration list is read in a script execution mode so that adevice address where the FPGA accelerator card to be updated is located can be acquired; updating firmware of the FPGA accelerator card is acquired, and the FPGA accelerator card is found through thedevice address so that the updating firmware can be burnt into the FPGA accelerator card; the updating firmware is loaded so that the FPGA accelerator card can be updated. Compared with an artificialmode that the updating firmware is burnt to the FPDG accelerator card one by one, the firmware updating method achieves automatic corresponding updating of the FPGA accelerator card by a system through script running, so that the problem of relatively low artificial updating efficiency due to a large quantity of FPGA accelerator cards in a complex network device environment is solved, the error probability due to difference among updating firmware of numerous FPGA accelerator cards in artificial updating is lowered, and high availability of the FPGA accelerator cards is guaranteed. Furthermore, the invention further provides the firmware updating device and medium of the FPGA accelerator card. The firmware updating device and medium of the FPGA accelerator card also have the advantages.

Description

technical field [0001] The invention relates to the field of FPGA development, in particular to a firmware update method, device and medium for an FPGA accelerator card. Background technique [0002] The essence of FPGA is to improve the reusability of digital circuits and realize different circuit logic functions in a programmable way. [0003] With the continuous evolution of the FPGA structure and the continuous improvement of the technology, more and more resources are integrated in the FPGA, and the functions of the FPGA become more and more powerful. The difference between FPGA and CPU or GPU-based ordinary processors is that FPGA changes the internal circuit logic through programming, and its field of expertise is mainly digital signal processing. Since FPGA has abundant on-chip storage resources, it can greatly reduce The latency of accessing off-chip storage greatly improves computing performance. Since FPGA has high computing performance and performs computing ta...

Problems solved by technology

However, the current working environment of the FPGA accelerator card is often a cluster device with a complex network structure. Therefore, the firmware that needs to be updated for the FPGA accelerator card in different devices is different. The manual burning method not only greatly reduces the firmware update efficiency. , and it will also increase the possibility of firmware programming errors, making it difficult to ensure high availability of the FPGA accelerator card
