Abstract :
This paper proposed a high-resolution architecture to implement the CORDIC algorithm. The addition identities of the trigonometric functions are adopted to determine the range of sine/cosine functions from the domain [0, 2pi] based on that restricted in the domain [0, pi/8]. The shrinking in domain of sine/cosine functions leads to about 50% reduction on the size of ROM lookup table and a 1-bit improvement on the precision in the CORDIC implementation
