6.3.1. Master-Slave Architecture

Try these first

1. 1.

   What is the role of the Master device in a Master-Slave architecture?

   Hint

   Think about which device gives commands.

2. 2.

   Define Memory-Mapped I/O.

   Hint

   Consider how devices are accessed by the CPU.

3. 3.

   In a Master-Slave architecture, who initiates the data transfer?

   • CPU
   • VGA Peripheral
   • Both

   Hint

   Consider which device gives orders.

4. 4.

   Is HSYNC responsible for starting a new frame?

   • True
   • False

   Hint

   Review the roles of these signals.

5. 5.

   Discuss the potential issues that could arise if the timing of HSYNC and VSYNC are not correctly aligned in a VGA display.

   Hint

   Think about what each signal does and how they relate to each other.

6. 6.

   Design a simple system block diagram that illustrates how a VGA peripheral connects to a CPU within a Master-Slave architecture framework.

   Hint

   Think about the key components discussed and how they interact.
