  Flexible Power Management for Embedded Systems - Article

Embedded designers today are facing more and more pressure to increase battery life and at the same time offer more features. One only needs to look at the rapid increase of functionality in mobile handhelds for verification. It has become clear that battery chemistries are not improving at the needed rate to fulfill these requirements. This places the pressure squarely on silicon vendors to deliver better performance at lower power. As if this dilemma wasn’t challenging enough, designers face strict time to market requirements posed by shrinking design cycles.

Moreover, green movements are requesting a reduction in battery waste, which translates to embedded systems that require fewer battery changes. There are also government regulations (Example: Energy Star) across the globe to reduce stand-by current in appliances. The next generation of embedded systems is going to need extremely low active and sleep power consumption while simultaneously increasing the amount of flexibility and programmability needed to meet time-to-market requirements.
