COMP207P - Compilers
This database contains the 2017-18 versions of syllabuses. Syllabuses from the 2016-17 session are available here.
Note: Whilst every effort is made to keep the syllabus and assessment records correct, the precise details must be checked with the lecturer(s).
|Taught By||Earl Barr (100%)|
|Aims||This is a practical course whose primary goal is develop an understanding of the operation of compilers and the development and specification of computer-based languages. The course pulls together threads from underlying theory, most notably from logic and from data structures and algorithms, and builds on these a practical exercise in which students create a compiler of their own using commonly available compiler development tools.|
|Learning Outcomes||To be able to: build lexical analysers and use them in the construction of parsers; express the grammar of a programming language; build syntax analysers and use them in the construction of parsers; perform the operations of semantic analysis; build a code generator; discuss the merits of different optimisation schemes.|

The course has the following assessment components:
- Written Examination (2.5 hours, 80%);
- Coursework Section (20%).
To pass this course, students must:
- Obtain an overall pass mark of 40% for all components combined;
- Obtain a minimum mark of 30% in each component worth ? 30% of the module as a whole.
