This is known as Language Processing System. These programs are then fed into a series of tools and OS components to get the desired code that can be used by the machine. So we write programs in high-level language, which is easier for us to understand and remember. The hardware understands a language, which humans cannot understand. We have learnt that any computer system is made of hardware and software. It would be a difficult and cumbersome task for computer programmers to write such codes, which is why we have compilers to write such codes. To instruct, the hardware codes must be written in binary format, which is simply a series of 1s and 0s. Binary language has only two alphabets, 0 and 1. Hardware understands instructions in the form of electronic charge, which is the counterpart of binary language in software programming. Hardware is just a piece of mechanical device and its functions are being controlled by a compatible software.
Why to Learn Compiler design?Ĭomputers are a balanced mix of software and hardware. It includes lexical, syntax, and semantic analysis as front end, and code generation and optimization as back-end.
Compiler design covers basic translation mechanism and error detection & recovery. It is also expected that a compiler should make the target code efficient and optimized in terms of time and space.Ĭompiler design principles provide an in-depth view of translation and optimization process. PDF Version Quick Guide Resources Job Search DiscussionĪ compiler translates the code written in one language to some other language without changing the meaning of the program.
