Semester 2, 2009Tutorial 1

1. Name the available 3 computer subsystems and briefly describe them.

2. With aid of a diagram describe how the 3 buses connect the subsystems.

3. Illustrate the Von Neumann and Harvard computer architectures.

4. What are Microcontroller families? Include examples in the answer.

5. A microcontroller consists of a 16bit address bus and 8bit data bus. (One addressable location is 8bits long)

What is the maximum memory it can access? How many cycles does it take to access a 16 bit value from

memory?

6. Describe how you could use a microcontroller to automate a car window mechanism.
