Which of the following statements is/are true?a)Parallelism is high in...
Concept:
Option 1: Parallelism is high in the horizontal microprogrammed control unit as compared to a vertical microprogrammed control unit.
True, Parallelism is high in horizontal microprogramming as several operations on different registers can be performed simultaneously.
Option 2: Hardwired control unit is slower compared to the microprogrammed control unit.
False, a Hardwired control unit is faster as compared to the microprogrammed control unit as there won’t be a delay of fetch, decoding, and executing the control instructions in the case of the hardwired control unit.
Option 3: In 2’s complement sum carry flag and overflow are the same.
False, In unsigned numbers, carry out is equivalent to overflow. But in two's complement, carry out tells you nothing about overflow.
Option 4: In 2’s complement sum if the sum of two negative numbers yields a positive result, the sum has overflowed.
True, the Following are the rules for detecting overflow in a two's complement sum:
  • If the sum of two positive numbers yields a negative result, the sum has overflowed.
  • If the sum of two negative numbers yields a positive result, the sum has overflowed.
Otherwise, the sum has not overflowed.
Hence the correct answer is option 1 and option 4.
