19.1.1. Control Signals and Micro-instructions

Try these first

1. 1.

   What does the Program Counter signify in a CPU?

   Hint

   Think about the term 'next instruction'.

2. 2.

   Define Micro-instruction.

   Hint

   Recall what operations are referred to at a micro-level.

3. 3.

   What is the function of control signals in a CPU?

   • To manage power consumption
   • To dictate operations among components
   • To store data temporarily

   Hint

   Focus on how components work together in a CPU.

4. 4.

   The functionality of the Memory Function Completed (MFC) signal is to:

   • True
   • False

   Hint

   Think about what signals might affect instruction flow.

5. 5.

   Create a flowchart to visually represent the sequence of control signals generated during the execution of the instruction ADD R1, M.

   Hint

   Break down the instruction into specific steps to represent in each flowchart section.

6. 6.

   Design an FSM that handles both unconditional and conditional jumps, detailing transitions based on the zero flag status.

   Hint

   Think about how different conditions affect the flow of instructions within the CPU.
