4 cards from this section. Quick, good the night before a test.
What does the program counter (PC) do?
Think about what happens when an instruction is executed.
What is the function of the MBR?
Consider the role of memory transfers in fetching instructions.
What does the Program Counter store?
Think about the flow of instruction execution.
Boolean operation: The MAR must be filled before the MBR can fetch data.
Consider the sequence of operations during a fetch cycle.
Explain how data corruption can occur in the CPU if the MAR and MBR operations are not properly sequenced. Provide an example scenario.
Think about how timing in the fetch cycle influences the accuracy of instruction execution.
In a scenario where multiple instructions require simultaneous access to the CPU’s registers, how would this affect the operation of the fetch cycle? Discuss potential solutions.
Consider what properties are essential for a conflict-free environment in technology.
