Techniques for low energy software
The energy consumption of a system depends upon the hardware and software component of a system. Since it is the software which drives the hardware in most systems, decisions taken during software design has significant impact on the energy consumption of the processor. The paper focuses on decreasing energy consumption of a processor using software techniques. A novel compiler technique is proposed which reduces energy consumption by proper register labeling during the compilation phase. The idea behind this technique is to reduce the energy of the processor by reducing the energy of the instruction register (also the instruction data bus) and the register file decoder by encoding the register labels such that the sum of the switching costs between all the register labels in the transition graph is minimized. There is no hardware penalty since this is purely a compiler optimization. Results on benchmarks show that the energy consumption of the DLX processor can be reduced by 9.82% ...
