  • Overview

    Compiler Design and Implementation is a course that introduces students to some basics in the design and implementation of compilers. In this course, we are to teach the theory behind various components of a compiler and the programming techniques involved to put the theory into practice. ATS is the chosen programming languauge for implementation. We plan to start from language design and finish with a compiler that can generate some form of executable object code.
