16.2.3. Basic Steps Involved

Try these first

1. 1.

   What is the role of the program counter during a jump instruction?

   Hint

   Think about what needs to happen after an instruction is fetched.

2. 2.

   Differentiate between unconditional and conditional jumps in one sentence.

   Hint

   Consider what conditions need to be checked in conditional jumps.

3. 3.

   What type of jump instruction will always execute its jump regardless of conditions?

   • A. Conditional jump
   • B. Unconditional jump
   • C. Both types

   Hint

   Remember the definition of unconditional jumps.

4. 4.

   True or False: Conditional jumps always execute.

   • True
   • False

   Hint

   Think about the conditions that govern the execution.

5. 5.

   Design a piece of assembly code that includes both a conditional jump and an unconditional jump. Explain what they would accomplish in a practical application.

   Hint

   Think about scenarios where user inputs require validation.

6. 6.

   Given an initial PC value of 10 and an offset instruction to jump to address 20, calculate the resulting PC value after execution.

   Hint

   Remember, jumping means adding the offset to the original PC value.
