subarray memory coy problem

[concorpoly]

Hi, I read a PPT, NIDAYS 2004, I am confused with the following block diagram:

it said if the AAA wire is not connecte to the for loop node, then the time is very diferent with the time with AAA wire.  I tried, it is true. but I don't know the reason.

And I tried several times with different value constant linking to index port of subarray.vi , the times are different two. for example, 0 -- 115 ms,  1 --- 34 ms. 4 --- 295 ms.

Adding a little to the piece of info.

If you use

Tools >>> Profile >>> Show buffer allocations...

LV will put dots where the bufferes are created.

That option let you SEE the buffers rather than having to guess.

Have fun!
