The Long-distance Reconfiguration Design of FPGA Based on ARM

ABSTRACT

The task of this design is using the developing embedded technique, ARM to configurate FPGA, so that the reconfiguration of FPGA can without dedicated configuration software, and the configuration of FPGA can no longer to connect with a computer. Save the configuration file in the memory chip, connect the ARM system to the Internet and remote access service to download configuration file for the configuration of FPGA. In the later period of this design, process the FPGA contiguration file(format conversion, encrypt, decode, etc.), and popularize this method to different series of FPGA. So that, the reconfiguration of FPGA do not need to connect FPGA with a computer, only need to get the configuration file. In this paper, structure NFS file system of ARM and computer is succeed, so does the wired communication and the process of configuration file, and the SP1 communication between ARM and FPGA for configuration is achieved.
