High-Resolution Architecture for CORDIC Algorithm Realization

摘要：

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; 2π based on that restricted in the domain 0; π/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.
