26.2.1. Execution in terms of Micro Instructions

Try these first

1. 1.

   What is a micro instruction?

   Hint

   It's a low-level operation.

2. 2.

   Define explicit jumps.

   Hint

   Think about how 'jump' is written out.

3. 3.

   What is a key role of micro instructions?

   • To store data
   • To execute macro instructions
   • To compress files

   Hint

   What do they translate into?

4. 4.

   True or False: Implicit jumps are explicitly defined.

   • True
   • False

   Hint

   Consider how they are managed in code.

5. 5.

   Design a set of micro instructions needed to execute a macro instruction that multiplies two register values. Explain your design.

   Hint

   Break down multiplication as a series of adds.

6. 6.

   Create a scenario where both implicit and explicit jumps are necessary for executing a series of macro instructions. Describe the flow.

   Hint

   Map out how user input might affect flow.
