Optimizing Embedded Code with Target Function Libraries

4 Press Ctrl+B to generate code from your model.

The Real-Time Workshop Repo rt window opens on your desktop. Fo r

more information about the report, refer to “Creating and Using a

Code Generation Report” in the Real-Time Workshop E mbedded Coder

documentation.

5 Use model-to-code highlighting to trace the code generated for each block

with target function library applied:

• Right-click on a block in your model and s ele ct Real-Time

Workshop > Navigate to code from the context menu.

• Select Navigate-to-code to highlight the code generated from the block

in the report window.

Inspect the code to see the target function operator in the generated code.

For more information, refer to “Tracing Code Generated Using Your

Target Function Library” in the Real-Time Workshop Embedded Coder

documen ta t ion in the online Help system.

If a target function library replacement did not occur as you expected, use the

techniques described in “Examining and Validating Function Replacement

Tables” in the Real-Time Wo rks ho p Embedde d Coder documentation to help

you d etermine why the build process did not use the function or o perator.

Using a File Differencing Scheme

You can also review the target function library induced changes in your

project by comparing projects that you generate both with and without the

processor-speciﬁc target function library.

1 Generate your project with the default C89/C90 ANSI target function

library. Use

Create Project, Archive Library,orBuild for the Build

action in the

Embedded IDE Link CC options.

2 Save the project to a new nam e— newp roje ct1.

3 Go back to the conﬁguration parameters for your model, and select a target

function library appropriate for your processor.

4 Regenerate your project.
