An FPGA-based adaptive communication system that demonstrates Dynamic Function eXchange (DFX) using the Xilinx Zynq-7000 (XC7Z020) FPGA. The project implements runtime hardware reconfiguration by replacing communication modules using partial bitstreams, while the remaining system continues to operate.
Modern FPGA systems often require hardware updates during operation. Traditional FPGA reconfiguration requires programming the entire device, interrupting system operation.
This project demonstrates how Dynamic Function eXchange (DFX) allows only the required hardware module to be reconfigured during runtime, reducing downtime and improving FPGA resource utilization.
The design was implemented using Verilog HDL, Vivado Design Suite 2018.2, and verified on the ZedBoard.
