I need to design a logicworks circuit and hardware circuit that is an ALU and meets the following requirements
Inputs a and B and does the below functions and A and B are both 4 bit bumbers
Add A + B
Subtract A − B
and A AND B (bitwise AND)
or A OR B (bitwise OR)
nand A NAND B (bitwise NAND)
nor A NOR B (bitwise NOR)
SetLessThan 0001 if A < B, 0000 otherwise
SetGreaterThan 0001 if A > B, 0000 otherwise
The logical functions (and, or, nand, nor) are all bitwise. Cout is irrelevant
I can only use 74x153 multiplexers but I can use any AND or other functions but no more multiplexers
I figure if I can get the logic down I can design the circuit but the logic is hazy for me
