摘要： A mobile terminal and an application processor are provided. The mobile terminal includes a power management module, an application processor, a display driver chip, and a display panel. The power management module is used to output a power supply voltage to the application processor, the display driver chip, and display panel. The application processor includes a graphics processor, a graphics random access memory and a display serial interface, where the graphics random access memory is communicably connected with a codec overlay hardware of the graphic processor, and is used to receive and store an image frame outputted by the graphic processor. The graphic random access memory is communicably connected to the display serial interface to output a stored image frame to the display driver chip through a display serial interface. The display driver chip controls the display panel to display the received image frame.

摘要： A touch controller includes a processor and a memory coupled to the processor. The memory stores instructions that, when executed by the processor, cause the touch controller to: operate in an uplink power saving mode in which an uplink signal is transmitted with reduced power in response to reception of a suspend order from a host computer, and operate in a normal mode in which the uplink signal is transmitted with normal power in response to detection of a predetermined trigger during operation in the uplink power saving mode.

摘要： A host apparatus, into which a card having a nonvolatile semiconductor memory is inserted, issues a check command to the card. The check command instructs to send information on whether the card supports a termination process in which the card shifts into a state ready for a stop of power supply from the host apparatus.

摘要： An interconnect interface is applied between sockets or between dies. The interconnect interface includes a first transmitter (TX), a first receiver (RX), and an electrical physical layer (EPHY) coupled between the first TX and the first RX. The data provided by a first device is transmitted from the first TX to the EPHY and then received by the first RX to be retrieved by a second device. The first TX includes an arbiter for arbitrating between a plurality of channels of the first device to obtain data from the first device. The first TX includes a packet generator, which packs the data obtained from the first device into a packet to be transmitted through the EPHY. The first TX further includes a first buffer that backs up the data obtained from the first device for retransmission.

摘要： A total power requirement for a plurality of memory operations is estimated. It is determined that the total power requirement would meet a power budget. In response to determining that the total power requirement would meet the power budget, a power profile identifier associated with a first operation of the plurality of memory operations is adjusted. The first operation and the power profile identifier are issued to a memory device. The power profile identifier is used by the memory device to regulate an amount of power used when performing the first operation.

摘要： A power supply device includes circuitry to supply power to an information processing apparatus, acquire a detection result of a person by a sensor disposed at the information processing apparatus, output a first determination result indicating whether a first condition is satisfied, and output a second determination result indicating whether a second condition is satisfied. When the detection result indicates that a person is detected in a state where the information processing apparatus is in a power saving mode, the circuitry cancels the power saving mode based on the first determination result and the second determination result. In the power saving mode, the power supplied to the information processing apparatus is reduced as compared with a normal mode. The first condition relates to an operation receivable by the information processing apparatus, and the second condition relates to a situation around the information processing apparatus.
