12.2.5. Revisiting Single Bus Architecture

Try these first

1. 1.

   What is a single bus architecture?

   Hint

   Think about how components communicate with each other.

2. 2.

   What role does the program counter play?

   Hint

   Consider it as a pointer to future instructions.

3. 3.

   What does the program counter (PC) do?

   • Stores current instruction
   • Holds the address of the next instruction
   • Directs the ALU operations

   Hint

   Consider the memory address context.

4. 4.

   Control signals are crucial for which of the following?

   • True
   • False

   Hint

   Think about managing flow and operations.

5. 5.

   Explain the variations of control signals when performing an ADD instruction versus a LOAD instruction in a single bus architecture.

   Hint

   Think about what operations each instruction requires from the ALU.

6. 6.

   Create a flowchart depicting the entire process of instruction execution in a single bus architecture, highlighting the changes in control signals.

   Hint

   Break down each step logically.
