As semiconductor fabrication technology evolves into very deep sub-micron （DSM） level, power consumption has become the inevitable challenge in SoC design. In order to maximize the lifetime of portable system battery, SoC is required not only to be energy-efficient but also to work in an optimal and battery-aware manner. This paper intends to discuss some key technologies of SoC design from the above perspectives of view.展开更多

文摘The most supreme characteristic of SoC （system on chip） era is the high complexity of the chips; architecture and software design have become the indivisible part of chip design. As semiconductor fabrication technology evolves into very deep sub-micron （DSM） level, power consumption has become the inevitable challenge in SoC design. In order to maximize the lifetime of portable system battery, SoC is required not only to be energy-efficient but also to work in an optimal and battery-aware manner. This paper intends to discuss some key technologies of SoC design from the above perspectives of view.
