Using Asymmetric Single-ISA CMPs to Save Energy on Operating Systems

CPUs consume too much power. Modern complex cores sometimes waste power on functions that are not useful for the code they run. In particular, operating system kernels do not benefit from many power-consuming features intended to improve application performance. We advocate asymmetric single-ISA mul...
