Question 1.
What does the Program Counter (PC) do?
Show hintHide hint
Think about what keeps track of instruction execution.
Question 2.
Name the two registers involved in fetching an instruction after the PC.
Show hintHide hint
Consider which registers deal with memory addresses and data.
3Question 3.
What does the Program Counter (PC) do?
- Tracks next execution stage
- Contains address of the next instruction
- Stores temporary data
Show hintHide hint
Think about what leads the processor in fetching instructions.
4Question 4.
True or False: The Memory Address Register (MAR) holds both data and addresses.
- True
- False
Show hintHide hint
Different registers serve different functions in a processor.
Question 5.
Consider a scenario where a CPU is retrieving instructions for a computational heavy task. Describe how the fetch cycle works during such a task, and what steps are involved.
Show hintHide hint
Break down each register involvement and track the changes through the cycle.
Question 6.
How might CPU performance be affected if proper timing in the fetch cycle is not maintained? Discuss potential outcomes.
Show hintHide hint
Reflect on what happens when multiple processes want to access memory simultaneously without coordination.
