The current network learning resources mainly are organized by tree structure as lesson - chapter - section. But taking into account the law of human cognition, it should describe and organize the learning resources, and provide e-Learning services with the knowledge of smaller units of granularity. This paper presents a learning resources organization's overall architecture with knowledge points...
Aging effects (such as Negative Bias Temperature Instability (NBTI)) can cause the temporal degradation of threshold voltage of transistors, and have become major reliability concerns for deep-submicron (DSM) designs. Meanwhile, leakage power dissipation becomes dominant in total power as technology scales. While multi-threshold voltage assignment has been shown as an effective way to reduce leakage,...
The ever-increasing chip power dissipation in SoCs has imposed great challenges on today's circuit design. It has been shown that multiple threshold and supply voltages assignment (multi-Vth/Vdd) is an effective way to reduce power dissipation. However, most of the prior multi-Vth/Vdd optimizations are performed under deterministic conditions. With the increasing process variability that has significant...
CMOS process variability is a major challenge in deep-submicron SoC designs. The variations in transistor parameters are complicating both timing and power consumption prediction. This article surveys recent progress in the statistical high-level synthesis area.
The impact of process variations on circuit timing increases rapidly as technology scales. Consequently, it is important to consider timing variations at the early stages of circuit designs. Conventional high level synthesis relies on the worst-case delay analysis to guide the design space exploration, however, such worst-case timing analysis can results in overly conservative designs with pessimistic...
