Question 1

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.

💡 Hint: Remember how we incremented `R1` to access array elements.

Question 2

True or False: In indirect addressing, the operand's address is part of the instruction itself.

True
False

💡 Hint: Consider how indirect fetching impacts the instruction format.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given an instruction size of 32 bits that includes an opcode and two operands, outline how the program counter would behave during execution.

💡 Hint: Assess the incremental movements from opcode to operand.

Challenge 2 Hard

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.

💡 Hint: Visualize accessing values at two different layers of memory.
