2019 (English)In: IEEE Transactions on Circuits and Systems Part 1: Regular Papers, ISSN 1549-8328, E-ISSN 1558-0806, Vol. 66, no 10, p. 3863-3873Article in journal (Refereed) Published
Abstract [en]

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.
