Peripheral devices on a USB network are accessed with a reduced frequency in order to save power dissipated by a CPU and other circuits when reading data needed by the host controller. Instead of possibly accessing devices each frame, peripheral devices are accessed during some frames, and not accessed during others. A USB host controller may have two or more modes, such as a low power mode and a regular mode. In the low power mode, USB devices are accessed during fewer than all frames, in the regular mode, USB devices are possibly accessed each frame. Mode selection may depend on whether battery power is used."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing system power consumption due to USB host controllers","description":"Circuits, methods, and apparatus that reduce the power consumed by data transfers initiated by a USB host controller.
