about designing an ALU
Hello everyone,
I have been trying to design a 4 bit ALU. I have designed it for some arithmetic and logical operations. Now I want to add the multiplication operation with my design. For that I am trying to design 4*4 multiplier. But the problem is it's giving me 7 outputs and the rest of the arithmetic and logical outputs are of 4 bits. So when I'll try to add my outputs in some mux , then there are 7 outputs from the multiplier and 4 outputs from the other portion.
If I use 4, 2*1 mux then there are 3 other multiplication outputs are left. What should I do in such a situation?
Any kind of suggestions will be greatly apperciated.
Thanks,
amira
