26.5.2. Condition Select and Branch Address

Try these first

1. 1.

   What is a micro instruction?

   Hint

   Think about the basic building blocks of CPU instructions.

2. 2.

   Define an explicit jump.

   Hint

   Consider instructions that are clearly defined in a program.

3. 3.

   What defines an implicit jump?

   • It is part of the macro instruction.
   • It occurs without direct instruction.
   • It is always a conditional jump.

   Hint

   Think about programmability and efficiency similarities.

4. 4.

   True or False: Control signals determine which part of the micro program should execute next.

   • True
   • False

   Hint

   Consider how instructions are processed in sequence.

5. 5.

   You are designing a micro program that has both 'jump on zero' and 'jump on carry' instructions. How would you optimize them for efficiency in your shared micro routine?

   Hint

   Consider how shared processes can reduce redundancy.

6. 6.

   Explain what might happen if the control signals are incorrectly set, leading to unintended jumps in a program.

   Hint

   Think about the importance of accuracy in control signal setups.
