Abstract: A method for saving power is provided. The method is used in a slave device. The method includes receiving a first switch request indicating to switch a clock source from a first clock to a second clock when the slave device enters sleep mode. The method includes transmitting a first clock source signal indicating to switch the clock source from the first clock to the second clock to registers. The method includes switching the clock source from the first clock to the second clock to the registers according to the first clock source signal.

Abstract: A method for saving power is provided. The method is used in a slave device. The method includes receiving a first system power management interface (SPMI) write command from an external device via a SPMI bus when the slave device is in sleep mode. The method includes turning on a system clock in response to the first SPMI write command indicating to turn on the system clock. The method includes allowing the external device to access the slave device.

Abstract: A semiconductor die includes an on-die power switch and a target device. The on-die power switch includes a plurality of power input nodes, a power output node, and a switch circuit. The power input nodes receive a plurality of operation voltages from a plurality of different power sources, respectively. The power output node outputs a target operation voltage selected from the operation voltages. The switch circuit selectively couples one of the power input nodes to the power output node. The target device operates according to the target operation voltage supplied from the on-die power switch. The on-die power switch and the target device are separate circuit blocks of the semiconductor die.

Abstract: An over-drive controller applied to a display panel and a method for over-drive control are provided. The over-drive controller includes an analyzing unit and an over-drive delta value determining unit. The analyzing unit is arranged for analyzing information of a current pixel in order to generate an over-drive information. The over-drive delta value determining unit is coupled to the analyzing unit, and is arranged for determining an over-drive delta value according to the over-drive information. Herein the over-drive information includes a position information or a field information of the current pixel.
