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 Eurípides Montagne University of Central Florida 6

COP 3402 Systems Software Course outline (continued) Grading Policy: (20%) Exam #1 (20%) Exam #2 (25%) Final Exam (30%) Programming project. (5%) Recitations Each programming project will have a due date and points will be subtracted for submission after that date ( up to 2 days late, 20 % off; more than two days late, you get “ 0” for that program).

COP 3402 Systems Software An Introduction to Systems Software Eurípides Montagne University of Central Florida 9

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: Eurípides Montagne Text editors Compilers Loaders Linker Debugger Assembler Operating system University of Central Florida 10

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 Eurípides Montagne University of Central Florida 11

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 (low-level) It is used to debug executable programs and their related object code and source program. Eurípides Montagne University of Central Florida 12

Systems Software: Run-Time Environment Loader: Loads an executable code and starts its execution. Libraries: Precompiled programs that create 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.
