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.

Blocks

Complex to Magnitude-Angle HDL Optimized	Compute magnitude and phase angle of complex signal – optimized for HDL code generation using the CORDIC algorithm
Hyperbolic Tangent HDL Optimized	Computes CORDIC-based hyperbolic tangent and generates optimized HDL code
Magnitude-Angle to Complex	Convert magnitude and/or a phase angle signal to complex signal
Trigonometric Function	Specified trigonometric function on input
