I met some trouble when using CLA for parallel compution. The problem is that I don't know which register will change its value or state when CLA task is finished every time. I know a PIE interrupt is triggered when the CLA task finishes, for example 'PieVectTable.CLA1_1_INT'. But this PIE interrupt register state only changes once. How can CPU get the information when the CLA task finishes each time?

Hello,

It depends on your system. If you are using an interrupt, then the C28x would service the interrupt and re-enable the interrupt.

The CLA hands-on-workshop is very good at describing the CLA, how to develop code for it, and also how to debug it in Code Composer Studio. I think you will find it helpful. Here is the link to the workshop:
