Abstract

Power consumption remains a challenge in the design of 3G mobile phones. Although power-saving design is generally associated with the digital part of a multimedia terminal, careful partitioning between analogue and digital implementation can yield big power savings, particularly the audio and user-interface subsystems. This article suggests various power-saving strategies, illustrated by examples in the audio output, audio sample rate conversion, codecs, and touchscreen interface subsystems.
模拟对话[3G手机省电]
在3G手机的设计中,功耗仍然是一个挑战。虽然节电设计通常与多媒体终端的数字部分有关,但在模拟和数字实现之间进行仔细划分可以产生大量的节电,特别是音频和用户界面子系统。本文提出了各种节能策略,并通过音频输出、音频采样率转换、编解码器和触摸屏接口子系统中的示例进行了说明。
