22.5.2. Micro-program Memory Management

Try these first

1. 1.

   What is the function of the control function field?

   Hint

   Think of how instructions are sequenced.

2. 2.

   Name a device that selects inputs based on control signals.

   Hint

   What do we use to manage multiple data sources?

3. 3.

   What does the control function field manage?

   • Memory allocation
   • Program counter signals
   • Input/output operations

   Hint

   Consider what part of execution it defines.

4. 4.

   Is the branch address field used for sequential instruction processing?

   • True
   • False

   Hint

   Reflect on when branches occur.

5. 5.

   Design a flowchart depicting how a micro-program counter operates given different control signals. Include scenarios with both jump and increment operations.

   Hint

   Focus on conditional evaluations.

6. 6.

   Given a set of instructions using the terms discussed (control function, branch address, condition select), explain how the micro-program memory must accommodate these for efficient operation.

   Hint

   Consider space constraints and efficiency.
