6.2.2. Synthesis Objectives

Try these first

1. 1.

   What are control steps?

   Hint

   Think about the sequence of actions when a computer processes an instruction.

2. 2.

   Define control signals.

   Hint

   Consider what happens to coordinate components in the CPU.

3. 3.

   What are control steps?

   • A sequence of coding instructions
   • Procedural actions to execute instructions
   • Design elements of hardware

   Hint

   Consider the specific actions taken in a CPU.

4. 4.

   True or False? Hardwired control units offer flexibility in design.

   • True
   • False

   Hint

   Reflect on the nature of hardware implementations.

5. 5.

   Design a control unit that efficiently handles a mixed set of instructions, including arithmetic, data transfer, and branching. Outline the control steps and signals required.

   Hint

   Think about how each instruction type can be processed distinctly but efficiently.

6. 6.

   Critique the performance of a hardwired control unit against a microprogrammed unit in a complex computing environment. Identify strengths and weaknesses.

   Hint

   Consider specific scenarios where each type might excel or falter in performance.
