摘要

只提供摘要形式。随着2003年英特尔/spl reg/迅驰/spl trade/移动技术的推出,英特尔重新定义了移动计算,以提供出色的移动性能、集成的无线功能,同时实现终端用户所需的延长电池寿命和轻薄设计。在开发英特尔迅驰移动技术的过程中,英特尔制定了一个雄心勃勃的目标,即在使用6芯锂离子电池的“轻薄”级笔记本电脑的典型情况下,使电池续航时间至少达到3.5小时(210分钟)。与基于Intel/spl reg/ Pentium/spl reg/ 4处理器的系统相比,这将至少多一个小时的电池寿命。在2003年3月发布的英特尔迅驰移动技术笔记本电脑中,大多数都超过了这个目标,这些笔记本电脑的电池运行时间是移动个人电脑中最长的。然而,该行业正面临着新的挑战。当前的电池技术在容量上达到顶峰,而对新的移动PC功能和更高性能的需求正在推动更高的平均功耗。本次演讲将讨论低功耗芯片和平台设计的创新机会,以及更高密度和可再生能源,以实现8小时或更长时间的电池寿命,用于“全天”计算。我们将讨论目前用于在芯片和平台层面提供更低平均功耗的技术,(例如,电压和频率缩放技术用于目前的芯片,以提供按需性能,同时在处理器空闲时消耗最低的平均功耗。低功耗显示技术(如LTPS比传统显示器至少降低30%的功率),以及可能提供更高容量和可再生/快速充电源的替代电池化学物质也将被讨论。

Battery life challenges on future mobile notebook platforms
Summary form only given. With the introduction of Intel/spl reg/ Centrino/spl trade/ Mobile Technology in 2003, Intel redefined mobile computing to deliver the outstanding mobile performance, integrated wireless capability, while enabling extended battery life and thin and light designs that end users demand. In developing Intel Centrino Mobile Technology, Intel took an aggressive goal of enabling at least 3.5 hours (210 minutes) of battery life given typical usage of "thin and light" class notebooks with 6-cell lithium ion batteries. Compared with Intel/spl reg/ Pentium/spl reg/ 4 processor-M-based systems, this would be at least an hour more battery life. This goal was exceeded by the majority of the Intel Centrino mobile technology-based notebooks introduced at the launch in March 2003, with these notebooks delivering some of the longest battery run times available on mobile PCs. However, the industry is facing new challenges. Current battery technologies are topping out in capacity, while demands for new mobile PC capabilities and higher performance are driving higher average power consumption. This talk will address the opportunity to innovate on lower power silicon and platform designs as well as higher density and renewable power sources to enable 8-hour or greater battery life for "all-day" computing. Techniques used today to deliver lower average power at the silicon as well as platform levels will be discussed, (e.g., voltage and frequency scaling techniques are use in today's silicon to provide performance-on-demand while consuming lowest average power when the processor is idle, lower power display technologies such as LTPS reduce power by at least 30% over conventional displays) as well as alternative battery chemistries that may deliver higher capacity and renewable/quick rechargeable sources will also be discussed.
