Abstract :
An extension of the CORDIC (coordinate rotation digital computer) algorithm that makes it possible to compute the functions cos-1 , sin-1, √1-t2, sinh-1 cosh-1, and √1+t2 is presented. The algorithms are suitable for VLSI implementation and require only a slight modification of the original CORDIC algorithm
