Maximum Operating Frequency Self-Tuning System on FPGAs Using Dynamic Reconfiguration

Abstract

This paper proposes the use of a dynamic clock frequency reconfiguration technique to optimize the performance of a circuit by changing its clock frequency to achieve the maximum operating frequency. The proposed technique uses an FPGA reconfigurable clock generator circuit that changes the generated clock frequency for a circuit in real time. By systematically increasing the clock frequency and monitoring the response of the circuit, the real maximum operating frequency can be determined. The effectiveness of the proposed technique is demonstrated through simulation and experimental results with the development of an experimental system. The results show that it can accurately determine the maximum operating frequency of a circuit while maintaining its reliability and integrity.
