Simulink Fixed Point

Converting Floating-Point Designs to Fixed Point

Using Simulink Fixed Point, you can automatically convert a floating-point design built in Simulink, Stateflow, and DSP System Toolbox into an initial fixed-point design without changing any blocks in your model. You can then optimize the fixed-point design and benchmark the final fixed-point implementation against the original floating-point design. At any point in the development process, you can generate fixed-point C and HDL code for implementation on hardware for rapid prototyping or production.

Floating-Point to Fixed-Point Conversion Using Fixed-Point Advisor 7:54
Explore fixed-point models and use automated logging and scaling tools to refine the fixed-point data types for more optimized results.

The Fixed-Point Advisor generates an initial fixed-point design from a floating-point model, and the Fixed-Point Tool helps you further optimize the fixed-point scaling.
