Question 1.
What does the MPC do during instruction fetching?
Show hintHide hint
Think about where the microinstructions are stored.
Question 2.
What is the purpose of the Instruction Register (IR)?
Show hintHide hint
What do we need to decode an instruction?
3Question 3.
What does MPC stand for?
- Microprogram Control
- Microprogrammed Control
- Microprogrammed Processor
Show hintHide hint
MPC is involved in memory fetching.
4Question 4.
True or False: The Op-Code is directly related to the operation being fetched.
- True
- False
Show hintHide hint
Consider the function of Op-Code in instruction execution.
Question 5.
Design a microprogram that incorporates branching for both addition and subtraction operations, illustrating how common sequences can be reused.
Show hintHide hint
Think about what would be common before performing operations.
Question 6.
Evaluate a scenario where the instruction register fetches an invalid instruction. Discuss how the control unit responds and what optimizations could prevent such situations.
Show hintHide hint
Consider how common checks can ensure valid commands.
