You want processor less design ?

Either way you need an address generator and then a decoder for each address
that indicates #1's at that address and take that result and add it to total.....

In Verilog, counting and outputting the number of 1's in an 8bit input?

What I am trying to do in my mind is take 8 1-bit inputs and count the 1's. Then represent those 1's. 01010111 should output 0101 (There are five 1's from input) module 8to4 (in,out,hold,clk,res...

Hi,

I guess this is a school project.
So what hardware do you have?
What programming language do you use?
What size and irganisation is the PROM?
What interface does it use?
Do you ave any timing requirements?
