Energy efficiency is an increasingly critical consideration for engineers designing everything from smartphones to supercomputers. At this year’s International Solid State Circuits Conference (ISSCC) Intel presents multiple papers addressing energy efficiency and other topics. This includes a paper about a graphics execution core that achieves 40 percent higher peak energy efficiency, a 10x reduction in sleep-state power and 2.7X higher GFLOPS/W at near-threshold voltage. Another paper presents physically unclonable function (PUF) circuits that enable stable secure key generation with industry-leading energy efficiency and high immunity to probing attacks. Another paper demonstrates platform input/output circuits and interconnects with industry-leading energy efficiency and scalable performance. These are research papers but the work could ultimately lead to energy efficient SoCs and platforms with better graphics and enhanced security. See Intel’s full ISSCC 2014 press kit.
