Mobile Power Network for Ultimate Mobility without Battery Life Anxiety
Similar to the evolution from the wired Internet to mobile Internet (MI), the
growing demand for power delivery anywhere and anytime appeals for power grid
transformation from wired to mobile domain. We propose here the next generation
of power delivery network -- mobile power network (MPN) for wireless power
transfer within a mobile range from several meters to tens of meters. At first,
we present the MPN's concept evolution and application scenarios. Then, we
introduce the MPN's supporting technology, namely resonant beam charging (RBC).
As a long-range wireless power transfer (WPT) method, RBC can safely deliver
multi-Watt power to multiple devices concurrently. Meanwhile, the recent
progress in RBC research has been summarized. Next, we specify the MPN's
architecture to provide the wide-area WPT coverage. Finally, we discuss the
MPN's features and challenges. MPN can enable the ultimate mobility by cutting
the final cord of mobile devices, realizing the "last-mile" mobile power
delivery.Comment: 10 pages, 5 figure
Memory Performance Characterization of SPEC CPU2006 Benchmarks Using TSIM
AbstractThis paper uses TSIM, a cycle accurate architecture simulator, to characterize the memory performance of SPEC CPU2006 Benchmarks under CMP platform. The experiment covers 54 workloads with different input sets, and collects statistical information of instruction mixture and cache behaviors. By detecting the cyclical changes of MPKI, this paper clearly shows the memory performance phases of some SPEC CPU2006 programs. These performance data and analysis results can not only help program developers and architects understand the memory performance caused by system architecture better, but also guide them in software and system optimization
