10.2.2. ALU Operations

Try these first

1. 1.

   What does ALU stand for?

   Hint

   Think about the operations it performs.

2. 2.

   Why is it important to avoid contention in CPU operations?

   Hint

   Consider what happens when two people try to speak at once.

3. 3.

   What does an ALU primarily do?

   • Storage of Data
   • Execute Mathematical Operations
   • Manage Memory

   Hint

   Think about its role in calculations.

4. 4.

   True or False: Control signals can allow multiple registers to output to the bus at the same time.

   • True
   • False

   Hint

   Think about what happens when multiple voices try to speak at once.

5. 5.

   You are tasked with designing a basic ALU operation system that incorporates at least three registers. Describe how you would manage control signals to ensure no contention occurs.

   Hint

   Think about how you can sequence actions over a clock cycle.

6. 6.

   Create a flowchart that illustrates the process of adding a constant value to a register using the various components discussed in this section.

   Hint

   Consider the steps from loading the constant to output.
