Question: draw the diagram using block diagrams for adder and decoder...
Draw the diagram (using block diagrams for adder and decoder and logic gates for the logical unit) for a
simple 4-bit ALU that can compute the following:
(a) A and B and C and D
(b) A or B or C or D
(c) A + B + C + D
Develop a truth table to check the correctness for each component of your ALU.
