Q: Is the CLA independent from the C28x CPU? Can they be synchronized?

  • A:

    Yes.  Once the CLA is configured by the main CPU it can execute algorithms independently of the main CPU. The CLA has its own bus structure, register set, pipeline and processing unit.  In addition the CLA can access a host of peripheral registers directly. This makes it ideal for handling time-critical control loops but it can also be used for filtering or math algorithms.

    Synchronization is done by starting CLA execution either by a peripheral interrupt or by writing to a specific register.  In addition the CLA can interrupt the main CPU.

    Please refer to your device specific documentation for the list of CLA features available on your device.
