Fixed-Point Blockset    

What Is the Fixed-Point Blockset?

The Fixed-Point Blockset includes a collection of blocks that extend the standard Simulink® block library. With these blocks, you can create discrete-time dynamic systems that use fixed-point arithmetic. As a result, Simulink can simulate effects commonly encountered in fixed-point systems for applications such as control systems and time-domain filtering. The Fixed-Point Blockset includes these major features:

In addition, you can generate C code for execution on a fixed-point embedded processor with Real-Time Workshop®. The generated code uses only integer types and automatically includes all operations, such as shifts, needed to account for differences in fixed-point locations.

Exploring the Blockset

To open the main Fixed-Point Blockset library, type

at the MATLAB® command line, or right-click on the Fixed-Point Blockset listing in the Simulink Library Browser. The main library contains 12 sublibraries. Refer to Blocks--By Category.

You can double-click on any block icon in a library to see its parameter dialog box. Click the Help button to view the HTML-based help for that block.
