1.1 Introduction to Language Processor A language processor is a software which bridges a specification and execution gap. Language processing activities arise due to: The difference between software designer’s idea related to behavior of software and the manner in which these ideas are implemented.

Introduction to Language Processor The designer expresses the ideas in terms related to the application domain. To implement these ideas in terms related to execution domain. The difference between the two domain termed as semantic gap. Semantic Gap Application Execution Domain Domain

Introduction to Language Processor The semantic gap has many difficulties, some of the important ones being large development time and efforts, and poor quality of software. These issues are tackled through the use of programming language (PL). Software implementation using PL introduces a new domain as PL domain.

Introduction to Language Processor Now the semantic gap is bridged by the software engineering steps. The first step bridges gap between application domain and PL domain known as specification gap. While the second step bridges the gap between PL domain and execution domain as execution gap. Specification Gap Execution Gap Application PL Execution Domain Domain Domain

Introduction to Language Processor The specification gap is bridge by the software development team. While the execution gap is bridged by the designer of the programming language processor. Like compiler or interpreter. PL domain reduces the difficulties of semantic gap mentioned earlier. The language processor also provides a diagnostics capability which detects and indicates errors in its input. This helps in improving the quality of the software.

Introduction to Language Processor Language processor is a software which bridges a specification or execution gap. We use term language processing to describe the activity performed by a language processor. We refer to the program form input to a language processor as source program and its output as the target program. The language in which these programs are written are called source language and target language.

Introduction to Language Processor A range of LP is defined to meet practical requirements. A language translator bridges an execution gap to the machine language like assembler and compiler. A detranslator bridges the same as the language translator, but in the reverse manner. A preprocessor is a language processor which bridges an execution gap but not translator. A language migrator bridges specification gap between two PLs.
