Question 1.
What is the first step in the CPU instruction execution process?
Show hintHide hint
Think about where the instruction is stored before execution.
Question 2.
Define the term 'Fetch-Decode-Execute Cycle'.
Show hintHide hint
Break down the three main stages.
3Question 3.
What do the Fetch, Decode, and Execute stages process?
- Only data
- Only instructions
- Instructions and data
Show hintHide hint
Think about what the CPU needs to execute an operation successfully.
4Question 4.
True or False: Immediate addressing means the operand's value is known at compile time.
- True
- False
Show hintHide hint
Consider whether the data needs to be fetched from memory.
Question 5.
How does the choice of addressing mode impact the efficiency of CPU instruction execution?
Show hintHide hint
Consider the balancing act between speed and data capacity.
Question 6.
Design a hypothetical instruction that implements both direct and immediate addressing modes in a single operation. Describe how the CPU would process it.
Show hintHide hint
Think about how the CPU segments both types of data access in one instruction.
