Active power management for configurable processors

ARC International is one of the largest suppliers of configurable processor technology. It licenses patented configurable multimedia subsystems and CPU/DSP processors that are used to design differentiated products. They are optimized for use in systemson- chip (SoCs) that consume less power, are less expensive to produce and require protection from cloning.

The ARC Energy PRO flow presented here is a new technology for active power management. It can reduce the power requirement by as much as 4X and is based on the integration of hardware, software and EDA design processes. It is primarily aimed at applications for battery-operated portable devices in markets such asWiMAX, digital radio, medical devices, etc.

The flow described in this article is based on the Common Power Format (CPF). Translators that enable analogous strategies to be adopted using the Unified Power Format (UPF) will be available in due course.
