TMS320F28379D: CLA and absolute encoder in the fast current loop example codes

Part Number:TMS320F28379D

Dear Champs,

I am asking this for our customers.

1) CLA in FCL

How is CLA used in our FCL?

Can you explain why CLA can accelerate the computation?

(We cannot reason because even there are two cores (C28x/CLA), it seems CLA still needs to wait for C28x or C28x waits for CLA for the results.)

In our FCL library, it seems CLA codes are not open?

2) In FCL, QEP is used.

If absolute encoder (by CLB) is used rather than QEP, will the latency dominated by the absolute encoder?

We notice in FCL v2, there is encoder interface for Endat, Biss, and resolver.

Can Tamagawa be used as well?

Wayne
