Abstract

Northwestern researchers have developed a novel software technology called User-Driven Power Management.  This invention uses feedback from the end-user to dynamically maximize user-specific needs and satisfaction while minimizing power consumption.  It optimizes computing speed and power management specific for each user and software application by tracking several run-time inputs, which include physiological traits via biometric devices, personally correlated CPUs and HPCs, and computer video output.    Furthermore, User-Driven Power Management is capable of resetting minimum voltage levels as well by determining the minimum voltage needed to achieve stability at each combination of CPU frequency and temperature.  This additional feature greatly minimizes power consumption further.

Application

• Power Management for embedded processors in handheld devices and computers

Advantages

• Reduces average power consumption
• Resets minimum voltage levels
• Optimizes settings to an individual’s preferences
