Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
