Challenge Problems
Push your limits with advanced challenges
Design a detailed overview of how the CPU handles fetching the instruction to execute 'SUB R2, R3', and explain the role of each register involved in the process.
💡 Hint: Break down the steps one by one focusing on what happens at each stage.
Evaluate the efficiency impacts of using registers over memory access in CPU operations observable in 'LOAD R1, M' vs 'ADD R2, R3'. How does this affect execution time?
💡 Hint: Consider how often each operation accesses memory to weigh the execution time differences.
