Most Repeated & Expected 100% Sure Topic of GATE CS-GATE PYQs on Number System-2's Complement Arithmetic Overflow or Underflow. How to solve 2's Complement Arithmetic Questions.
Q 1.Consider a system that uses 5 bits for representing signed integers in 2's complement format. In this system, two integers A and B are represented as A=01010 and B=11010. Which one of the following operations will result in either an arithmetic overflow or an arithmetic underflow?
A A+B
B A−B
C B−A
D 2∗B
Q2.Let R1 and R2 be two 4-bit registers that store numbers in 2's complement form. For the operation R1+R2, which one of the following values of R1 and R2 gives an arithmetic overflow?
A R1 = 1011 and R2 = 1110
B R1 = 1100 and R2 = 1010
C R1 = 0011 and R2 = 0100
D R1 = 1001 and R2 = 1111
