Loading system and method based on remote FPGA

Abstract

A remote FPGA loading system and method are provided in embodiments of the present application, wherein the system includes a first PFGA and a Flash memory; The first PFGA obtains a first configuration code from the Flash memory and loads the first configuration code by itself; The first PFGA obtains a second configuration code from the Flash memory and loads the configuration code into a corresponding second FPGA based on a SelectMAP configuration interface; If the first PFGA obtains the update instruction based on the optical fiber network, updating the configuration code in the Flash memory; If the second configuration code in the Flash memory is updated, the first FPGA re-acquires the first configuration code and the second configuration code, and loads the first FPGA and the second FPGA accordingly. The technical proposal of the application can carry out remote program maintenance on the FPGA equipment in a complex environment, and shorten the overall maintenance time. Remote configuration and loading of FPGA programs via fiber optic networks eliminates the need to disassemble remote FPGA devices and saves maintenance costs.

Description

technical field [0001] The present application relates to the field of program loading systems, in particular to a program loading system that utilizes optical fiber remote control and loads programmable logic device FPGA through SelectMAP. Background technique [0002] At present, FPGA (programmable logic device) is more and more widely used in industrial design, but the reloading of FPGA devices generally needs to connect FPGA devices to computers, and use supporting download cables and software configured by manufacturers to complete. . This loading method has certain limitations. [0003] In a digital array radar, the FPGA device is typically located in the digital components of the radar antenna. Due to the large size of the radar antenna and the large number of components, if the traditional FPGA reloading method is used, the components need to be removed from the antenna, and the FPGA in the component needs to be individually configured in turn. This method is diff...
