Challenge Problems
Push your limits with advanced challenges
Analyze a scenario where a CPU uses a single bus architecture to execute a series of instructions. Discuss how many temporary registers would be needed and evaluate the impact on processing speed compared to a three-bus architecture.
💡 Hint: Consider how many data transfers occur in a series of operations and how a bottleneck could be created.
Design a flowchart demonstrating the data path from the memory through the MDR to the ALU and back. Highlight where processing occurs and identify the role of each component.
💡 Hint: Diagram each component step and make clear the flow of information.
