Question 1

Compulsory Question [30 marks total]

(a) Describe in your own words the functions of the Address, Data and Control buses of a

typical microprocessor based system. Use a diagram to illustrate your answer. [5 marks]

(b) Convert the number 205 10 to binary and hence convert to Hexadecimal (without the use of a

calculator). [5 marks]

(c) Compare the Von Neumann and Harvard architectures and identify their key differences

(use diagrams to illustrate the differences). Why might the Harvard architecture be faster for

a given clock speed? [5 marks]

(d) Explain what you understand by the term “parity bit” and show how a parity bit might be

used to detect errors with the ASCII character set. What are the two key disadvantages of

using parity coding? [5 marks]

(e) Write an 8051 assembly language program to implement a delay of 1000μs (you may

assume a system clock frequency of 12MHz). [5 marks]

(f) Describe the sequence of events that takes place when an interrupt is asserted in an 8051

microcontroller, with particular reference to ISR vectoring. [5 marks]

Question 2

(a) What is PCI Expresss, and why is it better than a conventional bus system? [ 4 marks]

(b) Draw a simple circuit diagram and timing diagram to describe how a handshake protocol is

implemented between a microprocessor and a peripheral device (e.g. memory IC).

[ 6 marks]

(c) Compare and contrast USB 2.0 and USB 3.0. Use diagrams where appropriate to describe

differences in the architecture and describe how the connector has been designed in USB 3.

to allow backwards compatibility. What is wireless USB? In the contetxt of wireless USB,

explain how UWB differs from conventional narrowband wireless communications in the

implementation of upcoming wireless UWB technology. [ 6 marks]

(d) Bluetooth uses a technique called spread-spectrum frequency hopping to minimise the risk

of interference from other devices in the same frequency band. What is frequency hopping

and how does it limit the effects of noise? [ 4 marks]
