System Programming and Compiler Construction [SPCC ]

SPCC (System Programming and Compiler Construction)

System Programming and Compiler Construction is semester 6 subject of final year of computer engineering in Mumbai University. Prerequisite for studying this subject are Data Structures, Theoretical computer science, Operating system. Computer Organization and Architecture, Microprocessor. Course Objectives of the subject System Programming and Compiler Construction are to understand the role and functioning of various system programs over application program.

To understand basic concepts and designing of assembler, Macro processor and role of static and dynamic loaders and linkers. To understand the need to follow the syntax in writing an application program and to learn the how the analysis phase of compiler is designed to understand the programmer‘s requirements without ambiguity. To synthesize the analysis phase outcomes to produce the object code that is efficient in terms of space and execution time. Course Outcomes of the subject System Programming and Compiler Construction are on successful completion of course learner will be able to identify the relevance of different system programs. Describe the various data structures and passes of assembler design. Identify the need for different features and designing of macros. Distinguish different loaders and linkers and their contribution in developing efficient user applications. Construct different parsers for given context free grammars. Justify the need synthesis phase to produce object code optimized in terms of high execution speed and less memory usage.

A system programming language is a programming language used for system programming; such languages are designed for writing system software, which usually requires different development approaches when compared with application software. Edsger Dijkstra refers to these language as Machine Oriented High Order Languages, or mohol. General-purpose programming languages tend to focus on generic features to allow programs written in the language to use the same code on different platforms. Examples of such languages include ALGOL and Pascal. This generic quality typically comes at the cost of denying direct access to the machine’s internal workings, and this often has negative effects on performance. In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name “compiler” is primarily used for programs that translate source code from a high-level programming language to a lower level language (e.g., assembly language, object code, or machine code) to create an executable program.
