摘要:
One or more snapshots of data stored over a period of time are maintained in a hybrid storage device comprising a magnetic disk and a solid state disk, wherein a selected snapshot stores information that allows recovery of data that is stored in the hybrid storage device at a selected point in time of the period of time. The hybrid storage device receives an input/output (I/O) command from a computational device. A category of a plurality of categories to which the I/O command belongs is determined, wherein the plurality of categories comprise writing to an unused block, writing to a used block, reading from an unused block, and reading from a used block. In response to determining the category to which the I/O command belongs, the I/O command is handled by one of the magnetic disk and the solid state disk based on the determined category.
摘要:
A circuit with power saving function connected to a LCD includes a display signal output module, to output a display control signal; a boosting circuit; a Content Adaptive Backlight Control (CABC) control module, to output a CABC signal; and a combining circuit, connected between the display signal output module and the CABC control module, to combine the display control signal outputted by the display signal output module and the CABC signal outputted by the CABC control module, then output a combined signal to an input port of the boosting circuit. The boosting circuit is configured to boost the combined signal and output a boosted combined signal to the LCD, thereby changing the backlighting of the LCD to save energy.
