It’s All About Compiler Design
General Information about Compiler Design:
The Compiler is a computer program that interprets the code written in a high-level language (Java, C++) to low-level machine language, for creating an executable program. Verifying the entire program to ensure the elimination of sequential and logical error is the principal task of a compiler.
The microprocessor interprets the signal only in binary format which is developed by electric changes. Therefore, we have to design a compiler for translating the source code into the signals on which hardware work. Faults produced due to incorrect compiler behaviour are utmost difficult to check. Therefore it’s imperative to ensure a correct Compiler Design.
The most important step in Compiler Design is the study of phases of the compiler. These are the series of steps through which information transfers from the code and get compiled to machine language.
Mainly two phases are there:
i) Analysis Phase- From the given source code an intermediate representation is created in this. Steps involved are Lexical analysis, Syntax analysis, Semantic analysis and Intermediate code generation.
ii) Synthesis Phase- From the intermediate representation, an equivalent target program is generated in this phase. It has two parts: Code optimization and Code generation.
What is the Need and Benefit of learning Compiler Design?
Compiler Design fundamentals provide a thorough understanding of transformation and optimization process along with error detection and recovery. These operations are needed for and provide numerous benefits like:
- Enhancing the speed and efficiency of the microprocessor.
- Giving instructions to other mechanical devices like robots. For this, a compiler is to be designed first. This may give new efficient technology to the world.
- Converting an entire program into another language.
- Understanding the performance issues of programming languages.
Areas Where Compiler Design Is Used:
The compiler is a mediator between Programming languages and computer. Any set of instructions which one wishes to give hardware require a Compiler Design first. Several other areas are there as well where Compiler Design finds its usage. A few of those can be listed as:
- Full implementation and better study of a programming language.
- Verification of code and elimination of errors.
- While working on a machine if a compiler is designed separately then there is no need to execute the program on that machine all the time. The response then can be simulated on a computer anywhere.
- Internal structures in memory can be created by Compiler Design.
