To develop their technique, the researchers ran experiments on millions
of combinations of processors and compilers optimised for particular
functions. They then used a statistical analysis technique to
automatically identify the pairings that lead to best performance and
energy efficiency. Designers can also use the tool to pinpoint the best
processors to use with their optimised compiler requirements.

Dr Timothy Jones, of the University of Edinburgh's School of
Informatics, who led the research, said: "Using our method would enable
designers to choose the best combination of components for their needs.
For consumers, this means faster, smaller devices, producing less heat
and with improved battery life. Overall, this means cheaper products on
the market quicker."

The research was funded by the Royal Academy of Engineering, the
Engineering and Physical Sciences Research Council and the European
Union,  will be presented at the International Conference on Compilers, Architecture, and Synthesis for Embedded Systems in Atlanta,
Georgia.
