Hello all,
I have been asked a question with respect to indexed addressing please see the attachment.
I don't know anything about indexed addressing as I have never done it before, however from what I have read about the value in the index register gets added to the base address?
If you know of any good basic examples I would be most appreciative.
Getting back to the attachment with the COP instruction the source is #N(N19:2)N19:3). Does this mean that the data from these registers is loaded into the Dest #11:20? If that is so is the data from (N19:2)N19:3) added/subtracted/multiplied/divided before it is sent to the Dest. I guess what i'm asking is how is the data from these two registers presented and sent to the dest of #11:20?
If some knowledgeable person could describe to me what is happening to the data so I can identify what one of my starting addresses is it would be great.
Thank you
