20.5.1. Differences from Macro Instructions

Try these first

1. 1.

   What is a macro instruction?

   Hint

   Think about operations like ADD or LOAD.

2. 2.

   What does the program counter do?

   Hint

   Consider its role in maintaining instruction order.

3. 3.

   What defines macro instructions?

   • High-level commands
   • Low-level operations
   • Control signals

   Hint

   Remember the role of macro instructions in programming.

4. 4.

   True or False: Micro instructions can be modified after being set.

   • True
   • False

   Hint

   Think about flexibility.

5. 5.

   Analyze how changing a macro instruction affects the associated micro instructions in a system that uses micro-programmed control.

   Hint

   Consider how memory storage impacts execution.

6. 6.

   Design a hypothetical situation where the program counter must jump to a non-sequential location based on a micro instruction. Explain the logic required.

   Hint

   Think about control signals guiding instructions.
