An embodiment includes an input circuit, an intermediate circuit, an output circuit, and an accumulator circuit. The input circuit can receive a set of input values, and can use a first set of degenerate rotators to generate a first set of intermediate values. The intermediate circuit can receive the first set of intermediate values, and can use a set of CORDICs (coordinate rotation digital computers) to generate a second set of intermediate values. The output circuit can receive the second set of intermediate values, and can use a second set of degenerate rotators to generate a third set of intermediate values. The accumulator circuit can receive the third set of intermediate values, and can use a set of accumulators to generate a set of output values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital architecture for DFT/IDFT hardware","description":"Embodiments of the present invention can provide circuits and systems for computing a discrete Fourier transform (DFT) or an inverse discrete Fourier transform (IDFT).
