Candidates will require experience of several of the following:
- CPU architecture (pipeline effects, cache behaviour, interrupt mechanisms, bootstrap mechanisms etc.)
- Porting/enhancing GNU C compiler tools (gcc, g++) and GNU binutils (gas, ld, etc.) to new processor targets.
- Advanced register allocation, loop optimization and code scheduling techniques.
- Code generation techniques for non-C source languages (eg using MATLAB to generate assembly language or C).
- Code analysis and tuning (examining compiled and/or hand written assembly language statically, or using pipeline simulator output).
- Determining optimizations/improvements. Working with applications groups to assist in these activities.
- GNU newlib development. Optimization of similar runtime libraries (for codesize/datasize etc)

Industrial or focussed academic experience involving processor toolchain development, involvement in porting tools such as compilers assemblers, linkers, and experience of tuning tools to application requirements.

The ability to demonstrate good communication skills, a methodical approach and solid engineering ability.
