Practice Questions
Test your understanding with targeted questions
What is the value of R1 after the first operation if it starts at 1?
💡 Hint: Increase the initial value by the displacement.
If R5 starts at 0, what will it contain after the first addition from memory?
💡 Hint: Consider the effective address calculated using R1.

If a processor's instruction set uses 32-bit addresses and R1 points to 0x1000 with a displacement of 4, what would be the effective address? Explain your reasoning.
💡 Hint: Break down the hexadecimal addition step.
Demonstrate how changing the displacement affects the total sum accumulated in R5 if R1 cycles through the first five array indexes starting at 1 with a displacement of 2.
💡 Hint: List the effective addresses sequentially.
