29.2.1. Arithmetic Logic Unit (ALU)

Try these first

1. 1.

   What does ALU stand for?

   Hint

   Think of what types of tasks it performs.

2. 2.

   List one type of operation that the ALU performs.

   Hint

   Remember it performs mathematical tasks.

3. 3.

   What does the ALU primarily perform?

   • Arithmetic operations
   • Logical operations
   • Both A and B

   Hint

   Think of both mathematical and logical tasks.

4. 4.

   True or False: A three-bus architecture requires more temporary registers than a single bus system.

   • True
   • False

   Hint

   Focus on how processes are handled differently.

5. 5.

   Design a flowchart that represents the processes in the three-bus architecture, including the interactions between the ALU, registers, and memory.

   Hint

   Start by identifying each component and their interconnections.

6. 6.

   Evaluate how the efficiency of ALU impacts the overall performance of a CPU when comparing different bus architectures.

   Hint

   Consider how delays can affect operations in a busy CPU.
