Description

The CLA Task block creates a (Control Law Accelerator) CLA task that executes a downstream function-call subsystem on the CLA core. CLA is a coprocessor that allows parallel processing. Utilizing the CLA for time-critical tasks frees up the main CPU to perform other system and communication functions concurrently.

You can specify the interrupt source to trigger the CLA task. You can create up to eight CLA tasks to execute on the CLA core.

For information about how to configure a CLA block to execute a downstream function-call subsystem, see Overview of CLA Configuration for C2000 Processors Using Subsystem.

Note

Not all TI C2000 hardware board variants support CLA. For instance, within the TI Piccolo F2805x processor family, only the F28055 and F28053 processors support CLA, while the F28054, F28052, F28051, and F28050 processors do not.

Examples

Using the Control Law Accelerator (CLA)

Use the Control Law Accelerator (CLA) available on some of the TI® processors using C2000™ Microcontroller Blockset.

Ports

Output

Port_1 — Function-call signal to a function-call subsystem or function-call model

scalar

The output triggers the CLA task that executes a downstream function-call subsystem on the CLA core.

Parameters

CLA task number — CLA task number executed on CLA core

1 (default) | integer in [1, 8]

The CLA task number that you want to execute on the CLA core.

CLA task trigger source — Source of CLA task trigger

Software (default) | peripheral interrupt

The software or peripheral interrupt source that triggers the CLA task to execute on the CLA core.

Wait until completion of task — Block C28x execution until CLA task is completed

off (default) | on

Select the parameter Wait until completion of task, for the software source to trigger the CLA task.

Enabling this will halt the C28x execution until all the pending CLA tasks are completed.

Dependencies

To enable this parameter, set the CLA task trigger source parameter as software.

Sample time — Frequency at which function-call subsystem is triggered

0.2 (default) | -1 | scalar

Set the frequency at which the function-call subsystem is triggered by the CLA task trigger source. To execute this block asynchronously, set this parameter to -1.

Dependencies

To enable this parameter, select the Software option in the CLA task trigger source.
