For more information about target function libraries in the build process, refer

to “Introduction to T arget Function Libraries” in the Real-Time Workshop

Embedded Coderdocumentation.

Using a Processor-Specific Target Function Library to

Optimize Code

As a best practice, you should select the appropriate target function library

for your processo r after you verify the ANSI C implementation o f your project.

Note Do not select the proc esso r-speci ﬁc target function library if you use

your executable application on more than one speciﬁc processor. The operator

and function entries in a library may work on more than o ne processor within

a processor family. The entries in a library usually do n ot work with different

processor families.

To use target function library for processor-speciﬁc optimization when you

generate code, you must install Real-Time Workshop Embedded Coder

software. Your model m ust include a Target Preferences block conﬁgured

for y ou intended processor.

Perform the following steps to select the target function library for your

processor:

1 Select Sim ulation > Conﬁguration Parameters from the model menu

bar. The Conﬁguration Parameters dialog box for your model opens.

2 On the Select tree in the Con ﬁguration Parameters dialog box, choose

Real-Time Workshop.

3 Use Browse to select ccslink_ert.tlc as the System target ﬁle.

4 On the Select tree, choose Interface.

5 On the Target function library list, select the processor family that

matches your processor. Then, click OK to save your chan ge s and close

the dialog box.
