Title
(M, p, k)-Friendly Points: A Table-Based Method for Trigonometric Function Evaluation
Abstract
We present a new way of approximating the sine and cosine functions by a few table look-ups and additions. It consists in first reducing the input range to a very small interval by using rotations with "(M, p, k) friendly angles", proposed in this work, and then by using a bipartite table method ina small interval. An implementation of the method for 24-bit case is described and compared with CORDIC. Roughly, the proposed scheme offers a speedup of 2 compared with an unfolded double-rotation radix-2 CORDIC.
