computer engineering: PLEASE HELP Design a 4-bit 2’s complement format adder/subtractor circuit that is also capable of indicating the occurrence of an overflow condition. The circuit has two 4-bit inputs, P and S, and a 1-bit input Op. The value of Op specifies whether the operation to be carried out is addition or subtraction. The outputs for the circuit are R (4-bit wide) and Ov (1-bit wide; Ov =1 indicates the occurrence of an overflow during the addition/subtraction process and Ov = 0 indicates that there is no overflow). Verify your design’s functionality with Multisim by performing both P + S operation as well as the P − S operation for each of the following pairs of P and S values: P = 0000 and S=0000 (i.e. P = 010 and S = 010) P = 0110 and S=0100 (i.e. P = 610 and S = 410) P = 1110 and S=1000 (i.e. P = −210 and S = −810) P = 1000 and S=0100 (i.e. P = −810 and S = 410) (Eight cases in total: Four P+S cases and four P-S cases). As an example, when P = −2 and S= −8 as in the third case above, P + S = −2 + (−8) = 1110 + 1000 in binary, and P – S = −2 − (−8) = −2 + 8 The report should contain the following: 1. A Problem statement or Objective statement 2. A Methodology section. In this section, you need to discuss your design approach. 3. A Discussion section.
