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, which is particularly suitable for the computation of FFTs of a high number of points. Moreover, the new CORDIC presents other advantages such as the simplification of the basic CORDIC processor used to calculate the micro-rotations, or an easy way to compensate the intrinsic gain of the CORDIC algorithm. Additionally, the VLSI implementation of the algorithm is a pipeline architecture with high performance in terms of speed, throughput and latency.
