DSP power-management techniques help achieve faster design cycles

摘要

Designing handheld, battery-powered systems that require DSP capability demands that a great deal of attention be paid to power consumption. Selecting the DSP that delivers all the necessary computing power yet fits within a design's power budget can make or break the design's market viability or send the design back to the drawing board. Most design engineers are already painfully aware, however, that the conventional approach to estimating power consumption for a DSP produces a gross approximation at best. As such, new approaches to managing power consumption with software and estimating power consumption are needed.
