Efficient Memoryless Cordic for FFT Computation [PDF]
, 2007 A new memoryless CORDIC algorithm for the FFT computation is proposed in this paper. This approach calculates the direction of the micro-rotations from the control counter of the FFT, so the area of the rotator hardly depends on the number of rotations ...
