CS 2304 System Software Important Topics & Tips for Nov/Dec 2012 Examination

Posted by Suhale Akther

(Bolded topics are very important.)

UNIT I INTRODUCTION

System software and machine architecture – The Simplified Instructional Computer (SIC) - Machine architecture - Data and instruction formats - addressing modes - instruction sets - I/O and programming

Note:

Study all the topics because this unit is very small.Questions can be expected from the SIC and SIC-XE,RISC,CISC,Machine Architecture

UNIT II ASSEMBLERS

Set 1:Machine dependent assembler features - Instruction formats and addressing modes – Program relocation - Machine independent assembler features

Set 2: Literals –Symbol-defining statements – Expressions - One pass assemblers and Multi pass assemblers - Implementation example - MASM assembler.

Note:

This unit contains assembler programs.. :( boring unit...the students who feel hard to study this)

1 pass and multi pass and MASM assembler programs..u can go for set 1..But my idea is study set 1 and have an idea about one and multipass assembler and masm assembler(imp 8m and 2m)

UNIT III LOADERS AND LINKERS

Absolute Loader –Machine dependent loader features - Relocation –algorithm for pass 1 and pass 2 of a loader.- Machine-independent loader features - Automatic Library Search – Linkage Editors – Dynamic Linking – Bootstrap Loaders - MSDOS linker.

UNIT IV MACRO PROCESSORS

Macro processor functions,Definition,Expansion ,Algorithm and data structures - Machine-independent macro processor features -Conditional Macro Expansion – Keyword Macro Parameters-Macro within Macro-Implementation example -MASM Macro Processor – ANSI C Macro language.

UNIT V SYSTEM SOFTWARE TOOLS

(confirm questions are text editor,editor structure or interactive debuggin system and some times user interface question wil come) Text editors - Overview of the Editing Process - User Interface – Editor Structure. - Interactive debugging systems  – User-Interface Criteria.

Tips:

1. Start from Unit 1 , unit 2, unit 4,unit 3 and finally unit 2.

2. Unit 1 and 2 is easy..try to cover all the topics..

3. Unit 2,3,4 have algorithms..so please practice it..

4. In this subject,all unit contains machine dependent and independent topic..its repeated question in sem...

5. Have more concentration on SIC,SIC-XE,RISC,CISC,pass assembler(one,multi,masm)linkage editor,absolute n bootstrap loader,MSDOS linker,macro(algorithm,masm macro,ANSI C),editor,interactive debugging.
