Question

 Design a 4-bit Arithmetic Logic Unit (ALU) according to the following specification. Follow the design shown during the lecture. Notice this table is different, though.

 a. Create the internal of 1-bit of the logic unit (It is recommended that you design the internal of a 4 to 1 MUX first, create a symbol for it and use it for creating the logic unit)

 b. Create a symbol for your logic unit and use four of them to make a 4-bit logic unit

 c. Create the internal of 1-bit of the Arithmetic unit (It is recommended that you design

 the internal of a Full Adder first, create a symbol for it and use it for creating the

 arithmetic unit)

 d. Create a symbol for your arithmetic unit and use four of them to make a 4-bit arithmetic unit

 e. Create a 4-bit, 2-1 multiplexer (use buses).

 f. Create a schematic diagram for the complete 4-bit ALU
