  author={Vassilis Paliouras and Konstantina Karagianni and Thanos Stouraitis},
A VLSI architecture for fast and accurate floating-point sine/cosine evaluation is presented, combining floating-point and simple fixed-point arithmetic. The algorithm implemented by the architecture is based on second-order polynomial interpolation within an approximation interval which is partitioned into regions of unequal length. The exploitation of certain properties of the trigonometric functions and of specific bit patterns that appear in the involved computations, has led to reduced… CONTINUE READING
