Use Digital Works to design and implement a 4-bit computer which carries out four functions on two 4-bit numbers A(a 3a2a1a0) and B(b3b2b1b0). The four functions are: i) Add the two 4-bit numbers; ii) Subtract the two 4-bit numbers using 2's complement; iii) Perform logical AND on the 4-bit numbers; iv) Perform logical OR on 4-bit numbers; The computer has an ALU that performs the four functions depending on the selected code. Use interactive inputs for the two numbers which are buffered in two 4-bit registers before the selected operation is carried out. The output is displayed in two 7-segment displays. Detect overflows in your additions so as to display the overflow number in the second7-segmant display. You will need to use two BCD (binary coded decimal) - to-seven-segment converters. Use edge-triggered D-Flip Flops (covered in Notes #5) to construct the two input registers (A & B). The constructed registers should have Load Enable pins and Clock input. The outputs from the ALU should show on two 7-segment displays where the first one is the low-order and the second one the high order (e.g. 4+9= 13, so 1 displays on the high order display and 3 displays on the low-order 7-segment display). A sum like 7 +1 = 8 should display as 08; you will need to use two BCD (binary coded decimal) - to-seven- segment converters. Avoid cases of overflows where the result can't be presented in the ALU. Use the material covered in Combinational circuits (Notes #4). [Hint: Figures 3.41 (Multiplexers), 3.69 (7-segment displays), 3.54, 3.72, 3.73, 3.74 and 3.75 are particularly relevant to this project. Additional information is found in Sequential Circuits (Notes#5)]. You must use Multiplexers to implement this project. Use Digital Works to construct your circuit and ensure your name appears in the Digital Works design template and sample runs as prove of your work (e.g. label the 7-segment displays with your name - this is mandatory).

![Use Digital Works to design and implement a 4-bit computer which carries out four functions on two 4-bit numbers A(a
3a2a1a0) and B(b3b2b1b0). The four functions are: i) Add the two 4-bit numbers; ii) Subtract the two 4-bit numbers
using 2's complement; iii) Perform logical AND on the 4-bit numbers; iv) Perform logical OR on 4-bit numbers; The
computer has an ALU that performs the four functions depending on the selected code. Use interactive inputs for the
two numbers which are buffered in two 4-bit registers before the selected operation is carried out. The output is
displayed in two 7-segment displays. Detect overflows in your additions so as to display the overflow number in the
second7-segmant display. You will need to use two BCD (binary coded decimal) - to-seven-segment converters. Use
edge-triggered D-Flip Flops (covered in Notes #5) to construct the two input registers (A & B). The constructed
registers should have Load Enable pins and Clock input. The outputs from the ALU should show on two 7-segment
displays where the first one is the low-order and the second one the high order (e. g. 4+9 = 13, so 1 displays on the
high order display and 3 displays on the low-order 7-segment display). A sum like 7+1 = 8 should display as 08; you
