Method and system for dynamic reconfiguration of FPGA functions in PCIe equipment

Abstract

Embodiments of the present invention provide a method and system for dynamic reconfiguration of FPGA functions in a PCIE device. The method includes: after the PCIE device is powered on, load the first FPGA logic file corresponding to the first service function, establish the first connection with the host computer, and notify the microprocessor to select the second service function when the host computer loads the second service function of the PCIE device. The FPGA logic file uses the second logic object code to perform global dynamic reconstruction on the FPGA; after the global dynamic reconstruction is completed, a secondary link is established with the host. In the embodiment of the present invention, by using the logic target code with different functions of the initial logic, the FPGA is globally dynamically reconfigured, and neither the host machine nor the PCIE device needs to be restarted. The device can be dynamically replaced with new known or unknown functions during normal work, which is more versatile, flexible, more scalable, and more applicable scenarios.
