| 20080276258 | Method and Apparatus for Dynamically Assigning I/O Device in Virtual Machine System - A method and apparatus for dynamic assigning I/O device in virtual machine system, the virtual machine system comprises a service OS, a hypervisor and at least one guest OS. The service OS contains a device model module, the device model module providing an access platform for I/O device to the guest OS. The guest OS access the device model module through the hypervisor. One device state module for dynamic reflecting the device's state is increased in the device model module, the device state module dynamic altering the register condition of the device in hardware space. It is possible to dynamic control the access to I/O device by the guest OS by using the control panel in the service OS to dynamic alter the device's state in the device state module. One agent module is increased in guest OS, for altering the device's state in guest OS anytime based on the change of the device state. | 11-06-2008 |

| 20110006750 | LOW POWER AND HIGH ACCURACY BAND GAP VOLTAGE REFERENCE CIRCUIT - A band gap voltage reference circuit includes a first band gap circuit configured to generate a first band gap voltage potential. A second band gap circuit includes a variable resistance. The second band gap circuit is configured to output a second band gap voltage potential based on a value of the variable resistance. A calibration circuit is configured to adjust the variable resistance of the second band gap circuit based on the first band gap voltage potential and the second band gap voltage potential. The first band gap circuit is shut down in response to the second band gap voltage potential being within a predetermined range of the first band gap voltage potential. | 01-13-2011 |
