1. Compulsory Question [40 marks total]
(a) Describe in your own words the functions of the Address, Data and Control buses of a
typical microprocessor based system. You may use diagrams where necessary. [5 marks]
(b) What is the function of the South Bridge in a modern PC motherboard? Use a diagram to
illustrate your answer. [5 marks]
(c) Name and briefly describe any 5 data types in typical computer systems and indicate the type
of applications they are most suited to. [5 marks]
(d) With the aid of a system block diagram showing a microprocessor and memory device,
describe the memory write operation. You should further illustrate your answer with a
timing diagram. [5 marks]
(e) With the aid of the attached Microconverter quick reference guide, describe the function of
the individual bits in the PSW. [5 marks]
(f) What is the difference between immediate addressing and direct addressing in 8051
assembly language? Illustrate your answer with sample code. [5 marks]
(g) Write an assembly language program to add the number 19 16 to the contents of memory
location 41, and store the result in Bank 3, Register 6 (you may need to refer to the
Microconverter quick reference guide at the end of this exam paper). [5 marks]
(h) Calculate the amount of time (in μs) required to process the following segment of 8051
assembly language (you may assume a clock frequency of 12 MHz): [5 marks]
MOV A,
ADD A, 16
MOV B, A
MUL AB
PUSH B
ADD A, B
MOV 36H, A
RET
2. (a) Draw a simple schematic of a modern multi-core microprocessor. Your diagram should
make reference to the cores, caches and buses. [4 marks]
(b) What are solid state drives? List 3 advantages and 3 disadvantages of solid state drives over
conventional hard disc drives. [6 marks]
(c) What are the advantages of using a SATA interface for hard disc drives? Why will SATA 3
challenge conventional hard disc drives? Can you suggest a solution? [6 marks]
(d) Compare and contrast the Von Neumann architecture with the classic Harvard architecture.
Use diagrams where appropriate to illustrate your answer [10 marks]
(e) List four key characteristics of flash memory [4 marks]
3. (a) What is STACK memory generally used for in a microprocessor system? How does the
STACK operate and how is it addressed? [6 marks]
(b) The Data Pointer (DPTR) is a particularly useful resource on an 8051 system. Explain what
the DPTR is, and suggest some applications that might particularly benefit from using the
DPTR. Use an example to illustrate your answer. [5 marks]
(c) Contact bounce is a common problem with switches and keypads. Describe what you
understand by the term “contact bounce” and explain how the effects of contact bounce can
be reduced. [5 marks]
(d) List four hardware and four software steps that you would take in debugging a
malfunctioning embedded system [8 marks]
(e) Port 0 of the 8051 microcontroller is an open drain port. Explain how the port pins of port 0
might “float” and suggest a suitable solution to the problem. Use a port pin schematic
diagram to explain your answer. [6 marks]
