If a transmission channel is used to connect FPGA and memory modules for high-speed data transmission, then data processing speed is improved, but impedance mismatch causes signal noise that degrades transmission quality
Solution Approach 1:
A damping resistor is introduced as an intermediary component in the transmission channel between FPGA and memory modules. This resistor serves as a mediator to match impedance levels, absorb signal reflections, and reduce noise, thereby improving signal transmission quality while maintaining high-speed data transmission capability
Solution Approach 2:
The damping resistor changes the electrical parameters (impedance) of the transmission channel at critical points. By adjusting the resistance value to match the characteristic impedance of the transmission line, the system optimizes signal transmission characteristics and minimizes reflections and noise
