Real-Time Workshop User's Guide

Optimizing the Model for Code Generation

There are a number of ways that you can optimize code generated by the Real-Time Workshop from your model, with respect to both memory usage and performance. This chapter discusses optimization techniques that are common to all target configurations and code formats. For optimizations specific to a particular target configuration, see the chapter relevant to that target.

Topics in this chapter include:

• General Modeling Techniques. Optimizations that you can use with any target configuration.
• Block Diagram Performance Tuning. Efficient use of look-up tables, accumulator constructs, and data types.
• Stateflow Optimizations. Optimization feature for modes containing Stateflow blocks.
• Simulation Parameters. Using options on the Simulation Parameters dialog box to optimize generated code.
• Compiler Options. Recommendations for use of your compiler in building more efficient executables.
