Default Re: Download Anna University CSE Fifth Semester Exam Paper

Here I am providing you question paper for Anna University CSE Fifth Semester Examination..

1. Write an 8085 assembly language program to multiply two 8-bit numbers.
2. What are the functions of the RST 6.5 and ALE signals of 8085?
3. Write down the functions of the ASSUME and EXTRN assembler directives.
4. Define the functions of the REPEAT and LOCK prefixes.
5. Distinguish between the maximum mode and minimum mode of operation of the 8086 processor.
6. What is a coprocessor? How is it useful?
7. 8253's OUT signal is to be used as a clock input of the desired frequency to a particular device. Is it possible? How?
8. How is a memory-to-memory transfer accomplished using 8237?
9. What are the addressing modes supported by 8051?
10. Write an 8051program to divide two 8-bit number.

PART B - (5 x 16 = 80 marks)
11. (a) (i) Discuss the architecture of the 8085 processor with a neat diagram (10)
(ii) Write an 8085 program to subtract one 4-digit decimal number from another. (6)

(b) (i) Discuss the interrupts of 8085 (10)
(ii) Write an 8085 program to find the largest of a set of n 8-bit numbers. (6)

12. (a) (i) Assume that a symbol table starting at location TABLE consists of 100 entries. Each entry has 80 bytes with the first 8 bytes representing the name field and the remaining 72 bytes representing the information field. Write an 8086 program sequence to search this table for a given name of 8 characters stored in NAME. If this name is found, copy the associated information to INFO: otherwise fill INFO with null characters.(10)

(ii) Discuss about the interrupts of 8086. (6)
(b) (i) Discuss the string primitives of 8086 with an examples for each. (10)

(ii) Write an 8086 assembly language program using string primitives to find out whether a given byte is in a string or not. If the byte is a part of the string, find the relative address of this byte from the start of the string. (6)

13. (a) A multiprocessor system consists of 2 modules with the following specifications:
Module 1 : 8086 with 8087 and a resident bus
Module 2 : 8086 with an I/O bus.

Draw a detailed block diagram showing the various components required and indicate the interconnections between the various components. Explain briefly how co-ordination and communication take place between the various masters.

(b) Discuss the maximum mode configuration of 8086 with a neat diagram, clearly pointing out the functions of the various signals

14. (a) With a neat diagram discuss the various modes of operation of 8255. Show how two 8255 chip can be connected in an connected in an 8086-based system to form a 16-bit port.

(b) With a neat diagram discuss the operation of a DMA controller. Show how such a controller can be connected in an 8086-based system.

15. (a) Discuss the architecture of the 8051 microcontroller with a neat diagram.

PART A - (10 x 2 = 20 marks)

1. Define 'management'.
2. List the functions of management.
3. What is planning?
4. Define MBO.
5. What are the types of organisation?
6. What is 'line relationship' in line and staff organisation?
7. What is positive motivation?
8. Define communication.
9. What is controlling?
10. Define productivity.

PART B - (5 x 16 = 80 marks)

11. (a) Explain scientific theories in management.(16)


(b) Explain the various schools of management thought.(16)

12. (a) Discuss the benefits and difficulties for MBO.(16)


(b) (i) What are the types of forecasting? (8)
(ii) Explain briefly briefly forecasting techniques.(8)

13. (a) (i) Describe formal and informal organisations.(8)
(ii) State and explain the principles of departmentation.(8)


(b) (i) Discuss various types of decentralization that is practiced in organisations(8)
(ii) What are the advantages of a decentralized organization.(8)

14. (a) (i) Describe the different theories of motivation.(8)
(ii) Write a note on the qualities of a leader.(8)


(b) (i) Discuss the different theories of motivation (8)
(ii) What is the role of electronic media in communication(8)

15. (a) Explain the role of computers in handling the information (16)


(b) (i) What are the essential conditions for Globazation? (8)
(ii) List out the obstracles in globilization and explain.(8)
