In many fields such as communication

aviation

aerospace and medical treatment

FPGA as the main controller is irreplaceable.The traditional update method of FPGA based on JTAG (Joint Test Action Group) has the problems of relying on special JTAG download cable and local development environment

poor loading stability and low transmission rate.This paper presents a technical scheme for remote update of FPGA based on Stratix series.This scheme ensures that the basic hardware circuit is the same as the traditional update method.The FPGA software can be updated through software function expansion

which makes the debugging

updating and maintenance of products more convenient.The engineering practice has proved that the updating efficiency is increased by about 10 times by using the remote updating method

and the technical scheme is stable and reliable.
