5 cards from this section. Quick, good the night before a test.
What is the purpose of control signals in a CPU?
Think about what commands are necessary for executing operations in a CPU.
Define a micro-program counter.
What keeps track of the instruction sequence being executed?
What is the function of the micro-program counter (MPC)?
Think about what component keeps the location of the next instruction.
The condition select field is used for:
Does this field check for conditions influencing program flow?
Analyze a scenario where a program encounters multiple conditional statements—how would the MCU manage control signals for branching in this case?
Consider how many conditions might exist and what order they're evaluated.
Propose an optimized design for a micro-program memory that reduces wastage in control signals—what features would it have?
Think about the balance desired between control signal number and memory efficiency.
