Hello!
Could you please describe, what output of hardware emulation in SDAccel environment mean and why it runs so long?
INFO: [SDx-EM 22] [Wall clock time: 11:46, Emulation time: 1.54685 ms] Data transfer between kernel(s) and global memory(s)

BANK1 RD = 0.000 KB WR = 0.000 KB
BANK2 RD = 0.000 KB WR = 0.000 KB
BANK3 RD = 0.000 KB WR = 0.000 KB

BANK3 RD = 0.000 KB WR = 0.000 KB
Each such bunch of four lines - means one launch of the kernel code or one predefined bunch of memory transfer or something else? I am pretty sure that hardware emulation is slower than real because of statistics or something like that? Is it true or there are some other reasons. And also what these Emulation time: 1.73858 ms relates to? Definitely I am waiting more than 2 ms for this output.
This is a basic stuff but this output is not described anywhere and I want to be sure that I understand what it shows.
