16.2. Handling Control Transfer Instructions

Try these first

1. 1.

   Define control transfer instructions.

   Hint

   Think about what these instructions do in a program.

2. 2.

   What is an unconditional jump?

   Hint

   Does it check any flags?

3. 3.

   What type of jump does not evaluate any conditions?

   • A) Conditional Jump
   • B) Unconditional Jump
   • C) Both

   Hint

   Think about the criteria for jumping.

4. 4.

   True or False: Conditional jumps always check the zero flag.

   • True
   • False

   Hint

   Consider the flexibility of conditional jumps.

5. 5.

   Given an unconditional jump instruction at address 10 that jumps to 200, explain what happens step-by-step.

   Hint

   Focus on the steps of fetching and executing jumps.

6. 6.

   Write a small assembly code snippet illustrating both conditional and unconditional jumps and explain how they differ.

   Hint

   Remember to think about the flag evaluations.
