Power/Energy Awareness in GCC

2013-04-15 Thread Ghassan Shobaki
Hi, Does GCC currently have any power/energy reduction optimizations or any performance optimizations that take power/energy consumption into account? We are currently working on a research project on instruction scheduling for low power (experimenting with different algorithms for minimizing
