Abstract :
The CORDIC algorithm is discussed, and modifications which have been found to make the basic algorithms more flexible are presented. Logic diagrams of circuits which implement the fixed-point computations of these modified CORDIC algorithms in a bit-serial fashion are introduced. This choice allows the hardware to be compact and regular, thus permitting the placement of many CORDIC processing elements on a single die
