Abstract :
A special-purpose ROM-based component is proposed to calculate x sin ( theta ) and x cos ( theta ). The method significantly reduces the memory requirement of look-up tables. Applying the method to the design of a co-ordinate rotator, a low-cost pipelined architecture is proposed that provides a through-put of 0.25 rotations per addition time.
