: : Just a little confusion about lab 4:

: : 1) To take the average isn't a division required?
: : If so, is there such a circuit predefined in MaxPluxII?
: : Or is is sufficient to use the '/' operator?

: Or on the other side of the coin, would it be possible to limit the size of the blocks to 16 and only 16 words (so that we could just shift the sum 4 bits right instead using real division)? My guess is that even if there was a division module in MaxPlusII it would be too slow and would not be able to compute what we want in one 10MHz cycle.

You can't assume that the number of words is always 16. See
my previous posting for hints on how to implement division
efficiently. And you're right, MaxPlusII has no macro for
division -- you're going to have to build your own solution.
