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.
|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|
This example shows how to use the Trigonometric Function block to compute the CORDIC approximation of sincos for a fixed-point input signal.
This example shows some of the main steps needed to design and evaluate a sine wave data table for use in digital waveform synthesis applications in embedded systems and arbitrary waveform generation instruments.
