This paper presents a constant-scale-factor radix-2-4-8 CORDIC algorithm for fast vector rotation and sine/cosine computation. The CORDIC algorithm is a well-known hardware algorithm for computing various elementary functions. Due to its sequential nature of computatin, however, significant reduction in processing latency is required for realtime signal processing applications. The proposed radix-2-4-8 CORDIC algotithm dynamically changes the radix of computation during operation, and makers possible the reductin in the number of iterations by 37% for 64-bit precision. This paper also describes the hardware implementation of radix-2-4-8 CORDIC unit that can be installed into practical digital signal processors.
