摘要
Abstract
FPGA chips have the advantages of high flexibility,fast speed and low cost,and have been widely used in all walks of life,espe-cially in areas with high requirements for real-time and reliability of the system,such as aerospace and nuclear power DCS.The FPGA chip firmware is generally written through the special JTAG debugger,but the FPGA device cannot be updated and maintained by the special JTAG device after large-scale engineering application.In order to facilitate large-scale application and later maintenance,this paper proposes a method based on MCU simulation JTAG to realize the upgrade and update of FPGA.The subcontract sending response mech-anism is designed to ensure the reliability of data download during the upgrade package download stage,and MCU simulation JTAG is designed to realize the upgrade and update of FPGA external Flash.The upgraded system will be used in the I/O equipment of NuCON nuclear DCS.It has great significance for the large-scale engineering application of equipment.关键词
