Question 1.
What is the purpose of a register in computing?
Show hintHide hint
Think about where the CPU stores data immediately for operations.
Question 2.
What does effective address calculation involve?
Show hintHide hint
Feel free to refer to the example involving `R1`.
3Question 3.
What is the role of R1 in our memory addressing operations?
- It holds the final result.
- It serves as an index for memory access.
- It's an irrelevant register.
Show hintHide hint
Remember how we incremented `R1` to access array elements.
4Question 4.
True or False: In indirect addressing, the operand's address is part of the instruction itself.
- True
- False
Show hintHide hint
Consider how indirect fetching impacts the instruction format.
Question 5.
Given an instruction size of 32 bits that includes an opcode and two operands, outline how the program counter would behave during execution.
Show hintHide hint
Assess the incremental movements from opcode to operand.
Question 6.
In an indirect addressing mode, the operand located at memory address 80FF contains the address 0010. If a value needs to be added to it, outline the steps to retrieve the final value.
Show hintHide hint
Visualize accessing values at two different layers of memory.
