Yair, Andy
Thank you for answering the query.
Andy,
I was just thinking what you suggested as it would be costly
affair to kick accelerator for single block.
I see that in an engine there has to be a sequence init -> (one
more more) update -> final - > cleanup, at least once even if the
block size is just right, correct?
How do I make sure that for single block it doesn't go thru
engine?
Thanks again!

Well, single block hashing is commonly faster in software, but hardware
should beat it on multi-block operations. In other words one should aim
for "synergetic" implementation engaging hardware only when it's
advantageous. A.
