Comparision

[john]

Hello,

I am trying to comapare two 14bit unsigned numbers. Now comparision is
easy but I have 10 macrocells available to do it.
So can anybody suggest me the best optimized way to do it!

Thanks
john

I wouldnt have though that there is a very big solution
space,comparison is comparison.Ten macro cells gives you I don't know
how many gates but more than you need.

That's tight.
Brute force I get 9 LCs in a maxii or 11 LCs in a max3.
If you can spare 15 clock ticks of time,
you could shift them through one bit registers
and set a flop on the first mismatch.
