  5. COP 3402 Systems SoftwareCourse 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 II University of Central Florida

  10. 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 run application software efficiently. Examples of systems software are: Text editors Compilers Loaders Linker Debugger Assembler Operating system University of Central Florida

  11. 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 University of Central Florida

  12. Systems Software: Program Development Environment • Text editor: Software that permits the creation and editing of • text (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. University of Central Florida

  13. 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 creates • a friendly interface between the user and the computer system.
