| Abstract(in English) | Fast Fourier transform (FFT) is the arithmetic algorithm to do discrete Fourier transform at high speed on the computer. It is applied in a wide field like the voice analysis and the image analysis, etc. Hardware-based FFT processing has been under investigation, and many FFT processors are implemented using semiconductor integrated circuits based on various algorithms. However, a large amount of circuit operations are necessary in the FFT processor, and their power consumption becomes serious problems. Single flux quantum (SFQ) FFT processor has potential to solve the problem because of its ultra low power consumption and high-speed operation. In this study, we designed and implemented a radix-2 butterfly processing element for the FFT processor, and examined its high-speed operations by on-chip high-speed tests. |
