Bhumika Keyur Shah

This collection by Bhumika Shah begins with the introduction of language processors and phases-passes of a compiler. It then goes on to give a basic overview of the phases such as Lexical Analysis Phase, Syntax Analysis Phase, Semantic Analysis Phase, Intermediate Code generation Phases, Code Optimization Phase, Code Generation Phase, Symbol Table, Error Handling and the Sample Output of all the phases. The last part of the collection helps you gain an understanding of the types of errors that compiler can generate and the construction of compiler in detail.

This fascinating talk is on how Bhumika Shah became an educator and a teacher. She starts by stating reasons as to why she teaches on Unacademy, followed by her main domains and her first experience being a teacher.

UTalk: How I Became An Educator

In this lesson, educator explains briefly about the course, Introduction to Compiler Design. As this unit continues she details the benefits of this course to students. ​​Then one can know the major topics which will be covered in this course as she lists all the concepts which will be discussed.

Overview of the Course: Introduction to Compiler Design

This lecture focuses on Introduction to Language Processors and Compiler. To write an efficient and bug-free program, understanding of Compiler design is essential. And this lecture is the first step towards exploration of the world of Compilers.

Introduction To Language Processors And Compilers

In this lesson, Bhumika Shah begins by explaining the difference between Phase and Pass and the phases of a compiler. It then sheds light on analysis phases such as lexical analysis, syntax analysis and semantic analysis; intermediate code generator phase, code optimization phase and the code generation phase. The last part of the lesson gives an overview of the phase to pass relationship and how many passes can be made. 

Compiler - Phases And Pass: Differences & Analysis Phases

The lesson begins with an introduction to the lexical analysis phase, the input of the source language program and output of the list of valid tokens. It then highlights the basic definitions of a lexeme, a token, and pattern. Lastly, the lesson gives examples of pattern and states the lexical errors which can occur.

Basics Of Lexical Analysis Phase

In this lesson, educator explains the relationship of semantic analysis phase with syntax analysis and intermediate code generation. She also elucidates how the grammar of syntax analysis phase is utilized in the semantic analysis phase. Further, the roles of semantic analysis phase are elaborated. The attribute and the errors of semantic phase are​ also explained in detail.

Basics of Semantic Analysis Phase

This lesson deals with the concepts pertaining to the fundamentals of syntax analysis phase. As the lesson instigates educator explains about syntax analysis by briefing about lexical analysis, syntax analysis, and semantic analysis. The key essentials such as the s​econd phase of the compiler, grammar, and parsers to understand syntax analysis phase are discussed. Lastly, she also highlights some syntax errors as well.

Fundamentals​ of Syntax Analysis Phase

This lesson completely concentrates on the basics pertaining to intermediate code generation phase. The complete process of intermediate code generation phase is elucidated and the inputs and output of this phase have been explained in detail. One will know the significance of this phase as the educator has highlighted them with illustrations. She also shed light on the types of intermediate codes with appropriate examples.

Fundamentals​ of Intermediate Code Generation Phase

This lesson renders complete details on the fundamentals of code optimization phase. The educator explains the process of code optimization phase and one will learn about the input and output of the same. Then she sheds light on the types of code optimization which are machine independent and machine dependent. She also briefs about the pee hole optimization and elucidates about optimization transformations. She also hints about the next phase which will be discussed.

Basics of Code Optimization Phase

This lesson begins with the explanation of Code Generation Phase. The educator also explains how Code Generation phase is associated with the previous phase and the further processing. Further in the lesson various outputs generated by Code Generation Phase are being discussed along with a graphical representation. Also,​ learn about the code generation process, Machine Dependant Code Optimisation and much more, in this lesson.

Fundamentals of Code Generation Phase

This lesson begins by discussing what is a symbol table with a comprehensible explanation of the same. It thereby discusses various aspects related to the Symbol Table such as symbol table entries, its implementation types. The lesson thereby elaborates upon Linear List Implementation, Binary Search Tree Implementation, Hashtable Implementation which are basically the implementation types of Symbol Table.​

Fundamentals of Symbol Table

This lesson elaborates upon the concept of Error Handler and how it works. The lesson talks about the three phases of compiler error report. Further in the lesson light​ is throw upon different kind of errors and the error recovery​ strategies.

Basics of Error Handler

This lesson is the concluding lesson of this course. The lesson sheds light on Compiler, Lexical Analysis,  Syntax Analysis, Semantic Analysis, Intermediate Code Generator, Code Optimisation, Code Generation and the conclusion. Each and every concept is explained in a very comprehensible​ manner.

Conclusion: Sample Output of all the phases
