16 Bit Multiplier

Multiplies two 16 bit binary integers

The Wallace Tree and final stage Kogge-Stone Parallel Prefix Adder make this multiplier blazing fast.

This multiplier is crazy fast, the one I did was only 56 ticks althought using wallace tree and CLA final adder, really impressive!

Really great!
Why did you decide on a Wallace Tree and not a Dadda Tree?

how do you change the picture?

So I really don't play this game much cus it seems a bit pointless but, what is this? It interests me.

19 ticks?! Awesome!

I threw together a quick test to time them both.

Both were maxed out (my 16x16 vs your 15x15)

Mine completed in 19 ticks
(1 tick for the 16x16 matrix, 2 ticks per Wallace stage, and 6 ticks for the final sum)

Yours completed in 56 ticks.


Throw them both in a world and see what you come up with.

How fast is this in ticks, i got one too and id want to test these 2 against each other

I might come back to multipliers later and build a 16 bit Dadda Multiplier which will reduce the number of logic gates used.
