Question 1.
What are the three main steps in the instruction execution cycle?
Show hintHide hint
Think about the processes involved in processing an instruction.
Question 2.
Is 'ADD 5' an example of immediate or indirect addressing?
Show hintHide hint
Consider where the operand is located.
3Question 3.
What is the first step of the instruction execution cycle?
- Decode
- Fetch
- Execute
Show hintHide hint
Think about what happens before processing any operation.
4Question 4.
In indirect addressing, where is the actual operand located?
- Within the instruction
- In a nearby memory location
- At the address specified by the instruction
Show hintHide hint
Consider the steps involved in accessing the operand.
Question 5.
You are designing a computer architecture for a high-performance gaming system. Discuss the pros and cons of using immediate versus indirect addressing in your instruction set.
Show hintHide hint
Think about performance needs for gaming versus potential memory limitations.
Question 6.
Create an instruction execution cycle diagram illustrating fetch, decode, and execute steps along with handling an interrupt. Highlight the saving of the program state during the process.
