Given below are two statements:

Statement $I$: Hardwired control unit can be optimized to produce fast mode of operation

Statement $II$: Indirect addressing mode needs two memory reference to fetch operand

In the light of the above statements, choose the correct answer from the options given below

  1. Both Statement $I$ and Statement $II$ are true
  2. Both Statement $I$ and Statement $II$ are false
  3. Statement $I$ is correct but Statement $II$ is false

option A is correct ans 

hardwired control techniques, the control signals are generated by means of hardwired circuit. The main
objective of control unit is to generate the control signal in proper sequence

        Advantages of Hardwired Control unit:

  1. It is faster than the microprogrammed control unit.
  2. It can be optimized to produce the fast mode of operation                                                     Disadvantages of Hardwired control unit:
  3. Instruction set, the control logic is directly implemented.
  4. Requires change in wiring if the design has to be controlled.
  5. An occurrence of an error is more.
  6. It requires a more chip area, therefore, it is a costlier control unit.

Indirect addressing mode needs two memory references to fetch operand as address of operand is not given in instruction but address field contains address where  address of operand is stored
