Squeeze play: Wring the power out of your design

摘要

LOWER SYSTEM-POWER DISSIPATION is not a design constraint just for battery-powered applications; it is also a primary concern for many high-performance wired systems. The processor or processors you use in an embedded design may represent a relatively small amount of the system's overall power budget, but your decisions regarding the system and software architecture can significantly impact the overall processing performance, power consumption, and EMI (electromagnetic-interference) performance. For battery-powered systems, lower overall power consumption can mean your design benefits from a longer battery life, or it can enable you to select smaller batteries to minimize your system's size, weight, and cost.
