25.6.1. Key Clustering Rules

Try these first

1. 1.

   What is a micro program?

   Hint

   Think about how the CPU operates at a fundamental level.

2. 2.

   Define horizontal micro programming.

   Hint

   Consider the relationship between the number of signals and word length.

3. 3.

   What is the primary purpose of micro programming?

   • To execute software applications
   • To control CPU operations
   • To manage memory

   Hint

   Think about the function of a CPU.

4. 4.

   True or False: Vertical micro programs have longer instruction lengths.

   • True
   • False

   Hint

   Consider what compression does to length.

5. 5.

   Design a micro program that utilizes both horizontal and vertical coding techniques based on the signals available in a hypothetical CPU architecture.

   Hint

   Consider the signal frequency and critical paths in CPU design.

6. 6.

   Evaluate the efficiency of micro programming in a system that uses only vertical micro programs compared to a hybrid approach.

   Hint

   Relate back to key concepts of speed vs space efficiency.
