Computer System Architecture - Microprogrammed Control
10. Which of the following statements are true for horizontal micro- instruction encoding?
- A
If there are kcontrol signals, every control word stored in control memory (CM) consists of k bits, one bit for every control signal.
- B
Parallel activation of several micro-operations in a single time step can be performed.
- C
Parallel activation of several micro-operations in a single time step cannot be performed.
- D
None of the above
- Option : A.B
- Explanation : In horizontal microinstruction encoding, there is one separate bit for every control signal. Hence any number of control signals can be activated simultaneously.
