Fixed-Point Blockset

Why Use the Fixed-Point Blockset?

The Fixed-Point Blockset allows you to efficiently design control systems and digital filters that you will implement using fixed-point arithmetic. With the Fixed-Point Blockset, you can construct Simulink models that contain detailed fixed-point information about your systems. You can then perform bit-true simulations with the models to observe the effects of limited range and precision on your designs.

You can configure the Fixed-Point Settings interface to automatically log the overflows, saturations, and signal extremes of your simulations. You can also use it to automate scaling decisions and to compare your fixed-point implementations against idealized, floating-point benchmarks.

You can use the Fixed-Point Blockset with Real-Time Workshop to automatically generate efficient, integer-only C code representations of your designs. You can use this C code in a production target or for rapid prototyping. You can also use the Fixed-Point Blockset with Real-Time Workshop Embedded Coder to generate real-time C code for use on an integer production, embedded target.
