Overview

Real-time execution proﬁling in Em bedded IDE Link CC sof twa r e uses a set

of utiliti es to support proﬁ ling for synchronous and asynchronous tasks, or

atomic subs ystem s, in your generated code. These utilitie s record, upload, and

analyze the execution proﬁle data.

Execution proﬁler supports proﬁling your code two ways:

• Tasks—Proﬁ le your project according to the tasks in the code.

• Atomic subsystems—Proﬁle your project according to the atomic

subsystems in your model.

Note To perform execution proﬁling, you mu st generate your project from a

model in Simulink modeling env ironment.

When you enable proﬁling, you select wh eth er to proﬁle by task or subsystem.

To proﬁle by subsystems, you must conﬁgure your mod el with a t least one

atomic subsyste m. To learn more about creating atomic subsystems, refer to

“Creating Subsystems” in the online help for Simulink software.

The proﬁler generates output in the following formats:

• Graphical d isplay that shows t ask or subsystem activation, preemption,

resumption, and completion. All data appears in a MATLAB graphic with

the data notated by model rates or subsystems and execution time.
