25.1. Introduction to Micro Programs and Optimization

Try these first

1. 1.

   What is a micro program?

   Hint

   Think about the role of the CPU in executing tasks.

2. 2.

   Name the two types of micro programs.

   Hint

   Consider how they differ in structure.

3. 3.

   What does a horizontal micro program generally sacrifice for speed?

   • Memory Efficiency
   • Processing Power
   • Instruction Variety

   Hint

   Think about what makes it quicker and what is lost in that process.

4. 4.

   True or False: A vertical micro program is faster than a horizontal micro program.

   • True
   • False

   Hint

   Consider the trade-off characteristics we've discussed.

5. 5.

   Given a CPU architecture with 5 registers (each with 2 signals) and 3 system registers, calculate the total number of signals, then suggest a clustering method for optimizing memory.

   Hint

   Remember to analyze the nature of conflicts in signal usage.

6. 6.

   Evaluate the impact of using only vertical micro programming versus a hybrid approach in terms of speed and memory efficiency. Discuss the trade-offs involved.

   Hint

   Reflect on the consequences of prioritizing one aspect over another in system design.
