CORDIC Algorithms in Simulink

CORDIC algorithm operations in Simulink^®

CORDIC (COordinate Rotation DIgital Computer)-based algorithms are some of the most hardware-efficient algorithms because they require only iterative shift-add operations. The CORDIC algorithm eliminates the need for explicit multipliers, and is suitable for calculating a variety of functions.
