Operations like logarithm and exponential can be efficiently carried out by the CORDIC algorithm. Iterative computations are used by the CORDIC method to estimate the intended outcome. The algorithm may need more iterations, which would increase the computing time, depending on the degree of accuracy...
A novel method for computation of the CORDIC (coordinate rotation digital computer) algorithm is presented that is especially well suited for high throughput real-time signal processing applications. A transformation of the original CORDIC algorithm is derived which results in a partially fixed iteration...
