Abstract:
A method, an apparatus, and a system for online migrating from a physical machine to a virtual machine are provided. The method including: after a target virtual machine is created, started, and suspended by a virtualization platform VMM Host, initially synchronizing data of a memory page from a source physical machine to the target virtual machine at a second time point; monitoring the operation of updating the memory page since the second time point; incrementally synchronizing data of the updated memory page in the source physical machine to the target virtual machine, and stopping monitoring when an increment value of the updated memory page in the source physical machine is less than a first threshold; and calling the virtualization platform VMM Host to resume the target virtual machine to a running state. The effect of smoothly switching services from the source physical machine to the target virtual machine is achieved.
Abstract:
A liquid crystal display device includes a first polarization plate, a first birefringent film atop the first polarization plate, an optically compensated bend mode (OCB-mode) cell atop the first birefringent film, a refractive film atop the OCB-mode cell, a second birefringent film atop the refractive film, and a second polarization plate atop the second birefringent film. With this structure, any phase retardation of polarized light occurred during the propagation of the polarized light from the first polarization plate to the second polarization plate is compensated by the first birefringent film, the refractive film, and the second birefringent film and a substantially cross-shaped radiation pattern of full viewing angle is obtained in an actual measurement at the light outgoing surface of the liquid crystal display device, proving the liquid crystal display device has effectively improved the problem of restricted viewing angle and provides good optical performance.

Abstract:
A write circuit for providing distinctive write currents to a chalcogenide memory cell is disclosed. The write circuit includes a current amplitude trim module, a current amplification and distribution module, and a write current shaping module. The current amplitude trim module provides a well-compensated current across a predetermined range of temperatures, voltage supplies and process corners intended for programming a chalcogenide memory cell. The current amplification and distribution module amplifies the well-compensated current in order to meet a programming requirement of the chalcogenide memory cell. The write current shaping module supplies an appropriate amount of write “0” current or write “1” current, based on the amplified current, to program the chalcogenide memory cell accordingly.
Abstract:
A current mode logic voter circuit includes three two-input split NOR gates. Each two-input split NOR gate receives a corresponding pair of input signals and generates a pair of first output signals responsive to the input signals. A three input split NOR gate is coupled to the two-input split NOR gates to receive the first output signals and generates a second pair of output signals responsive to the first output signals from the two-input split NOR gates. The two and three-input split NOR gates can be formed from current mode logic buffer circuits, and in one embodiment in the three-input split NOR gate the buffer circuits are hardened.
Abstract:
A read reference circuit for a sense amplifier within a chalcogenide memory device is disclosed. The read reference circuit provides a reference voltage level to the sense amplifier for distinguishing between a logical “0” state and a logical “1” state within a chalcogenide memory cell. In conjunction with a precharge circuit, the read reference circuit generates a selectable read reference current to the sense amplifier in order to detect the logical state of the chalcogenide memory cell. The precharge circuit precharges the bitlines of the chalcogenide memory cell before the sense amplifier detects the logical state of the chalcogenide memory cell.
