Abstract

The invention provides a FPGA (Field-Programmable Gate Array) device upgrading system based on an Ethernet link, which belongs to the technical field of computers. The upgrading system comprises a to-be-upgraded FPGA device and a computer, wherein a microprocessor reads a binary program file pre-stored in the computer through an Ethernet interface; the microprocessor writes the binary program file to a memory through an SPI bus; an FPGA chip reads the binary program file stored in the connected memory through the SPI bus; and the FPGA is power-on again to complete upgrading. In comparison with the prior art, when the FPGA device is upgraded, remote upgrading can be realized without opening the shell of the FPGA device, and the upgrading is more convenient.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for upgrading an FPGA device based on an Ethernet link. Background technique [0002] FPGA (Field-Programmable Gate Array), the field programmable gate array, is a product of further development on the basis of programmable logic devices. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gate circuits of the original programmable devices. The circuit design completed with hardware description language (Verilog or VHDL) can be quickly burned to FPGA for testing after simple synthesis and layout, which is the mainstream of modern IC design verification technology. The FPGA circuit can be quickly finished, and can be modified to correct errors in the program to upgrade the program. Therefore, with...
