Question 1.
What are the three main steps in the instruction cycle?
Show hintHide hint
Think of the acronym FDE.
Question 2.
What does immediate addressing mean?
Show hintHide hint
Consider if the number is stated explicitly in the command.
3Question 3.
What is the first step in the instruction execution cycle?
- Decode
- Execute
- Fetch

Recall the FDE cycle!
4Question 4.
True or False: In indirect addressing, the instruction contains the address of the operand directly.
- True
- False
Show hintHide hint
Consider how information is referenced!
Question 5.
Design a simple instruction set including at least two types of addressing modes. Determine how each instruction affects the CPU's performance based on your design.
Show hintHide hint
Think about efficiency in terms of memory access times.
Question 6.
Explain the implications of interrupts on real-time systems, comparing to non-real-time systems in terms of instruction execution.
Show hintHide hint
Consider industries like gaming and medical systems where timing is crucial.
