IDTdevelops new architecture for power effecient regulator designs used in computing sys

Integrated Device Technology Inc has developed HyperGear technology, a power savings and performance enhancement architecture for high frequency voltage regulator designs targeted at computing applications, 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. This new technology saves cooling costs in cloud-based datacenter environments and extends battery life in portable applications as per IDT.

According IDT, HyperGear algorithm has included in it'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, also HyperGear automatically and safely over-clocks the CPU to improve performance and concurrently shorten the duration required for processing and 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 says IDT.

"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."

IDT explains that HyperGear uses a proprietary two-wire serial interface bus to link IDT CPU power management chips to the IDT clock console and using Voltage ID (VID) information and monitoring the output load, HyperGear will 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.
