26.2.2. Jump Instructions

Try these first

1. 1.

   Define macro instruction.

   Hint

   Think about what high-level programming languages do.

2. 2.

   What is an implicit jump?

   Hint

   Remember, it happens without an explicit command.

3. 3.

   What is a macro instruction?

   • A low-level command
   • A high-level directive
   • An optimization technique

   Hint

   Think about what signifies high-level programming.

4. 4.

   True or False: Implicit jumps require explicit commands in the code.

   • True
   • False

   Hint

   Consider the distinction between explicit requirements and automation.

5. 5.

   Consider a scenario where you need to create a micro program that involves both implicit and explicit jumps for a control flow. Describe the flow and highlight the decisions made.

   Hint

   Think about the roles each type of jump play as you describe their purpose.

6. 6.

   You've been asked to optimize a routine that uses both kinds of jumps. What criteria would you use to decide which jumps to optimize?

   Hint

   Consider how often different paths are taken when optimizing.
