Performance evaluation of a FFT using adpative clocking

This paper presents an experimental evaluation on the feasibility of using an adaptive clock to enhance the performance of a Fast Fourier Transform (FFT). The FFT is implemented on an FPGA and results are simulated using commercial EDA tools. Dynamic power consumption and processing speed are compared to a standard FFT implementation using a fixed clock. Results show that using a dynamically variable frequency clock offers a potential speed improvement while maintaining energy efficiency.
