5. COP 3402 Systems Software Course outline
Course Outline: This course is designed to provide a fundamental understanding
of real and virtual machines as language processor. We will study the processor
as an instruction interpreter. Compilers, assemblers, and virtual machines will be
presented as systems software for program development. An introduction to
Operating system will be given.
Course Topics: introduction to compilers and interpreters, virtual machines,
computer architecture and assembler, loaders and linkers, macro-processors,
run time environment and operating systems
Prerequisites:
COP 3502 – Computer Science I

What is Systems Software?
Systems Software consists of a set of programs that support
the operation of a computer system and help, the programmer,
to simplify the programming process and create an
environment to run application software efficiently.
Examples of systems software are:
Text editors
Compilers
Loaders
Linker
Debugger
Assembler
Operating system

11. University of Central Florida
Systems software can be classified in two groups:
1.- Software to create a program development environment
Text editor
Compiler
Assembler
Linker
Debugger (low-level)
2.- Software to create a run-time environment
Operating system
Loader
Dynamic Linker
Program libraries

12. University of Central Florida
Systems Software: Program Development Environment
Text editor: Software that permits the creation and editing of
text files (i.e. application programs).
Compiler: Translates programs written in a high level
language to object code or machine code.
Assembler: Translates programs written in assembly language to
object code or machine code.
Static Linker: Combines and resolves references between object
programs and creates the executable code.
Debugger It is used to debug executable programs and their
(low-level) related object code and source program.

13. University of Central Florida
Systems Software: Run-Time Environment
Loader: Loads an executable code and starts its execution.
Libraries:
Precompiled programs the creates a set of functions for use by
other programs.
Dynamic Linker:
Loads and links shared libraries at run-time
Operating system:
An event driven program that make an abstraction of the computer
system. The operating system handles all resources efficiently,
creates an environment for application programs to run, and provides a friendly interface between the user and the computer system.
