| Abstract(in English) | The fast Fourier transform is the algorithm which transfer the function in the time domain into the frequency domain. It is used in the analysis of the sound and the image processing and so on. In the medical application, wireless communication and radio astronomy, the real-time FFT is highly demanded. Therefore hardware-based FFT processing has been under investigation. We are developing the FFT processor using SFQ circuits. In the FFT processor, memory access at high throughput is required for the large number of calculations at high speed. In this study we propose an SFQ-FFT processor system with high speed memories and implement the prototype computing unit including shift-register memories. |
