초록

This paper deseribes the design of a vector-coordinate rotation processor and the apporoximate evaluations of sine and consine based upon the use of residue number systems. The proposed algorithm results in a considerable improvement of computational speed as compared to the CORDIC algorithm. According to the results of computer simulation, the mean error of sine and cosine is 0.0025, and the mean error of coorcinate rotation arithmatic is 0.65. The proposed processor has the efficiency for the design and fabrication of integrated circuits, because it consists of an array of identical lookup tables.
