Further Programming or ability to program in Java.
Module learning outcomes
- Explain the structure of a conventional compiler, showing the interfaces between the phases.
- Use formal syntactic specifications for common high-level language constructs in the construction of the analysis phase of a compiler.
- Implement modules of a complete compiler for a simple source language and a simple target architecture.
- Explain the key characteristics of the instruction set of a simple modern processor and illustrate how it can be used in compiler-generated code.
