IDT Technology Reduces Motherboard Power Consumption, Boosts CPU Performance SimultaneouslyJuly 26, 2011 by Jeff Shepard
Integrated Device Technology, Inc. (IDT®) announced that it has developed a power savings and performance enhancement architecture for high frequency voltage regulator designs targeted at computing applications. The new patent pending "HyperGear" technology dynamically adjusts the CPU voltage, peripheral bias voltage, and CPU clocking frequency based on the CPU usage demand and can provide more than 10% efficiency improvement while simultaneously boosting CPU performance. According to the company, this new technology saves significant power and cooling costs in cloud-based datacenter environments and extends battery life in portable applications.
An innovative HyperGear algorithm included in IDT’s power management ICs recognizes the need for higher CPU speed when running data-intensive programs such as games and videos, or during heavy internet traffic on cloud-based enterprise servers. Under these demanding conditions, HyperGear automatically and safely over-clocks the CPU to improve performance and concurrently shorten the duration required for processing. During rest periods, HyperGear scales down the clock frequency for improved efficiency. In sum, these dynamic frequency and voltage controls allow computers to run faster while reducing net energy consumption under typical operating conditions.
"IDT’s industry leadership in timing solutions combined with our power management expertise allow us to take a system-level approach to solving problems, bringing elements together to make big improvements," said Arman Naghavi, General Manager and Vice President of the Analog and Power Division at IDT. "Our HyperGear technology is a perfect example of how we can significantly improve efficiency and performance through communication between power management and clocking devices on the board along with innovative control circuitry within the devices. While the competition focuses on incremental power controller efficiency improvements, IDT’s system-level approach results in an order of magnitude better performance."
HyperGear uses a proprietary two-wire serial interface bus to link IDT CPU power management chips to the IDT clock console. Using Voltage ID (VID) information and monitoring the output load, HyperGear will dynamically adjust the CPU’s core voltage and clock frequency, without the need for additional external components or complex circuit design. IDT has started utilizing the technology on all current and future power management solutions that comply with industry standard specifications, such as VR12, making it easy to realize the benefits of a HyperGear solution on new and existing platforms.
