Question 1.
What is the function of a Micro-Programmed Control Unit?
Show hintHide hint
Think about what it directs in the CPU.
Question 2.
Define the Micro-Program Counter (MPC).
Show hintHide hint
Consider its tracking role in instruction execution.
3Question 3.
What is the role of the Micro-Program Counter (MPC)?
- Tracks current instruction address
- Stores control signals
- Manages memory allocation
Show hintHide hint
Consider what is being tracked by the MPC.
4Question 4.
True or False: Unconditional branches depend on the evaluation of conditions to determine the next instruction address.
- True
- False
Show hintHide hint
Think about what distinguishes conditional from unconditional branches.
Question 5.
Given a sequence of instructions with multiple branches, devise how the MPC should update based on the zero and carry flags after execution.
Show hintHide hint
Review how flags influence MPC decisions.
Question 6.
Create a flowchart that illustrates the decision-making process for executing an unconditional branch instruction within a micro-program.
Show hintHide hint
Focus on the immediate effects of unconditional directives.
