What is the primary function of the micro-program counter (MPC)?
💡 Hint: Think about what the MPC is responsible for in instruction execution.
How does a multiplexer (MUX) operate in the control unit?
💡 Hint: Consider situations where you have multiple choices in a device.

Quick quizzes to reinforce your learning
What does the MPC do when instructed to jump to address '101'?
💡 Hint: Remember how loading works in condition checks.
True or False: The MPC automatically increments if no conditions are met.
💡 Hint: Consider what happens when conditions for decision-making are absent.

Challenge Problems
Push your limits with advanced challenges
If the MPC starts at address '002', and the control signal indicates to load '005', what will the MPC do, and how do the control signals influence this decision?
💡 Hint: Consider the actions dictated by control signals.
Design a simple pseudo-code to demonstrate how an MPC would operate through a loop until a certain condition (like a counter reaching 5) is met, and illustrate how signals change through each iteration.
💡 Hint: Think about an analogy where a driver loops until a destination is reached.
