An ethernet based remote system upgradation technique for FPGA based inaccessible digital systems

In modern digital systems, FPGAs are being increasingly used as they offer design flexibility and faster system implementation. Generally the FPGA firmware is upgraded via standard interfaces such as JTAG using lab programmer kits. But it's difficult to implement the same in case of remotely located FPGA based systems using such methods. Currently Ethernet is one of the most widely used communication interfaces for accessing remotely located digital systems. This paper proposes a novel method to upgrade firmware of an inaccessible digital system using standard TCP/IP protocols of an Ethernet link.
