نبذة مختصرة : In this paper, we present the first implementation of a 1 million-point fast Fourier transform (FFT) completely integrated on a single field-programmable gate array (FPGA), without the need for external memory or multiple interconnected FPGAs. The proposed architecture is a pipelined single-delay feedback (SDF) FFT. The architecture includes a specifically designed 1 million-point rotator with high accuracy and a thorough study of the word length at the different FFT stages in order to increase the signal-to-quantization-noise ratio (SQNR) and keep the area low. This also results in low power consumption. ; Funding Agencies|Swedish ELLIIT Program
