ABSTRACT
The article presents information on solving energy management problems in feature-rich portable devices. The increasing demand for data-intensive features in portable devices is increasing the strain on the battery, and incremental improvements in battery technology cannot keep up with power demands that are orders of magnitude higher than before. This creates a dilemma for design engineers that demands a radical re-thinking of power management and a comprehensive approach to developing new systems. This is the exact problem chat PowerWise technology solves through adaptive voltage scaling. Together with ARM'S Intelligent Energy Manager, National's new PowerWise technology provides the lowest power consumption in the industry for digital processors. PowerWise technology is a system-level approach that reduces the power consumption of a digital Very Large Scale Integration chip. PowerWise technology embeds a synthesizable AMBA-compliant core called the Advanced Power Controller onto the digital chip.
