Energy-Efficient Embedded System Design at 90nm and Below : A System-Level Perspective

High-Performance Computing : 6th International Symposium, ISHPC 2005, Nara, Japan, September 7-9, 2005, First International Workshop on Advanced Low Power Systems, ALPS 2006, Revised Selected PapersEnergy consumption is a fundamental barrier in taking full advantage of today and future semiconductor manufacturing technologies. This paper presents our recent research activities and results on estimating and reducing energy consumption in nanometer technology system LSIs. This includes techniques and tools for (i) estimating instantaneous energy consumption of embedded processors during an application execution, and (ii) reducing leakage energy in instruction cache memories by taking advantage of value-dependence of SRAM leakage due to within-die V th variation
