COMP30141: Compilers (2008-2009)
Any program written in a programming language must be translated before it can be executed. This translation is typically accomplished by a software system called compiler. This module aims to introduce students to the principles and techniques used to perform this translation and the issues that arise in the construction of a compiler.
A student successfully completing this module should be able to:
Understand the principles governing all phases of the compilation process. (A,B)
Understand the role of each of the basic components of a standard compiler. (A)
Have awareness of the problems of and methods and techniques applied to each phase of the compilation process. (A)
Apply standard techniques to solve basic problems that arise in compiler construction. (A,B)
Understand how the compiler can take advantage of particular processor characteristics to generate good code. (A,B)
Assessment of Learning outcomesAll learning outcomes are assessed by a 2-hour written examination.
Contribution to Programme Learning OutcomesA2, A3, B1, B3 mainly. A5, C5, D6 to some extent.
