Hello

I have a question about memory copy called block copy using UDMA without a DRU.

From what I understand, UDMA will transfer only TRs via PSI-L to DRU when I use a DRU.

Q) If I try to transfer using only UDMA without the DRU, data would be transfered to MSMC via PSI-L or CBASS in NAVSS ?

Best regards

Data transfer is agnostics to SW and I need to check with the design people for this.

BTW what is the intend of your question?

Hello, Sivaraj

Thank you for your reply.

I want to know how much faster the DRU works than the UDMA on block copy mode.

But I've recievied messange from another question. (Actually, you responsed that question. :) )

So this event could be resolved.

Best regards,

Yongsig.
