5 cards from this section. Quick, good the night before a test.
What is the first step of instruction execution?
Think about how a CPU starts processing an instruction.
Define 'operand' in the context of instruction execution.
What does the instruction act upon?
What is the main role of the Program Counter (PC)?
What does the PC do before an instruction is fetched?
True or False: The Instruction Register (IR) only holds data, not instructions.
What does the IR specifically store?
Write a detailed explanation of how the fetch-decode-execute cycle affects program performance. Include examples of how optimizing each stage can improve overall speed.
Think about each stage's contribution and how improvements would lead to better performance.
Analyze a scenario where an interrupt occurs during a long sequence of instructions. Describe the process and implications for the program's execution.
Consider how interruptions interact with ongoing tasks and the importance of restoring state afterwards.
