1. Design extra 1-bit outputs from the n-bit ALU for the four conditions codes Zero Flag, Sign Flag, Carry Flag, and Overflow Flag. Using the provided sheet, draw and label the additional logic required for each condition code (flag), all on one ALU diagram.

2. Describe the output of the ALU when Invert A = 1, Negate B = 1, and Operation ID = 10.

   • Write your answer as an arithmetic or Boolean/bitwise expression using A and B.
   • Your expression must use either arithmetic operators or Boolean/bitwise operators
   • .
