In this paper, we propose a new CORDIC algorithm and architectures which can generate close-to-optimum rotation sequences easily with small lookup table sizes. This new design is particularly suitable for the applications of adjustable length FFT. In all, the required number of shift-and-add operations for micro-rotations and scale-factor compensations is(More)
