TMS320F280049: CLA Interrupts without End-of-Task Interrupt

Christian Gienger

Part Number: TMS320F280049

Hi there,

i am using CLA to handle ADC results. I am getting into trouble when I try to not use an end-of-task interrupt triggered by the adc handling cla task.

Therefore my question is: Is an End-of-Task interrupt mandatory? Your CLA hands on workshop does not discuss this topic, it only provides the FIR filter example where an end of task interrupt is definitely used.

Best regards,

Chris

Hi Chris,

Please see the CLA Software Development Guide FAQ: https://software-dl.ti.com/C2000/docs/cla_software_dev_guide/faq.html#can-the-cla-send-an-interrupt-to-the-c28x

Whether the interrupt is needed on not will depend on the architecture of the system and the code.

The End of task interrupt is used to trigger the C28 when CLA task completes. Whether the interrupt is needed or not will depend on what is being done on the C28 side. If it is only being used to acknowledged the task and it does not impact any code executing on C28 then you don't need it. But if the C28 side is using the interrupt to do something specific in the application then it will be needed.

Thanks,
Ashwini

Hi Ashwini,
thanks for your hint! I obviously did not recognize this hint when I digged into the CLA Software dev guide.

Best regards, Chris
