Understanding Energy Consumption on the C 62 x

The emergence of portable computing devices and high-power processors has fueled recent interest in energy consumption. This paper examines how a processor consumes energy and a compiler can assist in energy conservation. Successfully transforming programs to reduce energy consumption is heavily dependent on the target machine and type of program. We examine a specific processor, the TMS320C6200 from Texas Instruments, and demonstrate how a compiler can reduce energy consumption for certain programs. We hope that our methodology can be used as a blueprint for future work on reducing energy consumption in other processors.
