Demos

You can find interactive Fixed-Point Toolbox demos in the MATLAB Help browser. Fixed-Point Toolbox software includes the following demos:

• Fixed-Point Basics — Demonstrates the basic use of the fixed-point fi object

• Number Circle — Illustrates the definitions of unsigned and signed two's complement integer and fixed-point numbers

• Binary Point Scaling — Explains binary point-only scaling

• Fixed-Point Data Type Override, Min/Max Logging, and Scaling — Steps through the workflow of using doubles override and min/max logging in the toolbox to choose appropriate scaling for a fixed-point algorithm

• Fixed-Point C Development — Shows how to use the parameters from a fixed-point MATLAB program in a fixed-point C program

• Fixed-Point Algorithm Development — Presents the development and verification of a simple fixed-point algorithm

• Fixed-Point Fast Fourier Transform (FFT) — Provides an example of converting a textbook Fast Fourier Transform algorithm into fixed-point MATLAB code and then into fixed-point C code

• Analysis of a Fixed-Point State-Space System with Limit Cycles — Demonstrates a limit cycle detection routine applied to a state-space system

• Quantization Error — Demonstrates the statistics of the error when signals are quantized using various rounding methods

• Fixed-Point Lowpass Filtering UsingMATLAB for Code Generation — Steps through generating a MEX function from MATLAB code, running the generated MEX function, and displaying the results

• Fixed-Point ATAN2 Calculation — Uses the CORDIC algorithm and polynomial approximation to perform a fixed-point calculation of the four quadrant inverse tangent

• Fixed-Point Sine and Cosine Calculation — Uses the CORDIC approximation functions to compute the sine and cosine of fixed-point data

To access these demos, click the Demos entry for Fixed-Point Toolbox in the Contents pane of the Help browser, or type demo('toolbox','fixed-point') at the MATLAB command line.
