  • Publication number: 20230420018
    Abstract: A data processor is for accessing a memory having a first pseudo channel and a second pseudo channel. The data processor includes at least one memory accessing agent, a memory controller, and a data fabric. The at least one memory accessing agent generates generating memory access requests including first memory access requests that access the memory. The memory controller provides memory commands to the memory in response to the first memory access requests. The data fabric routes the first memory access requests to a first downstream port in response to a corresponding first memory request accessing the first pseudo channel, and to a second downstream port in response to the corresponding first memory request accessing the second pseudo channel. The memory controller has first and second upstream ports coupled to the first and second downstream ports of the data fabric, respectively, and a downstream port coupled to the memory.

  • Publication number: 20160282950
    Abstract: A method for managing and controlling graphic user interface starts with an initial graphical user interface being displayed on a display device. When a request is made in a particular manner, it is determined that such request requires an update of the initial graphical user interface, and a substitute graphic user interface is generated. The substitute graphic user interface is a scaled-down replica of the initial graphical user interface. The substitute graphic user interface is displayed on the display device to replace the initial graphic user interface and so as to have the same functionality as the initial graphic user interface.

  • Patent number: 9450554
    Abstract: An electronic device and volume adjusting method detect ambient light and generate corresponding intensity signals via a sensor. Programs in a storage device, executed by at least one processor, cause the at least one processor to receive and sample light intensity signals and determine whether the ambient light level is changing. Time passing is counted if the ambient light level is changing, until the ambient light level stops changing. The counting of time stops when ambient light level stops changing and the counted time period is compared with a preset time period, a longer time period causes a volume adjusting command to be sent to a playback output device.

  • Patent number: 9440340
    Abstract: An electric rivet nut tool has a motor, a torque adjuster and a control device. The control device drives the motor to rotate a driving shaft so as to set a rivet nut. The torque adjuster serves to adjust a preset torque value. When a torque generated by the driving shaft exceeds the preset torque value of the torque adjuster and it represents that the rivet nut setting job is completed, the torque adjuster then displace for the control device to detect the displacement and drive the motor to reversely rotate. Given the torque adjuster and the control device, the problems of being time-consuming, inefficient, increasing in cost and damage prone to rivet nut or motor upon setting rivet nut because of the manual switch of forward or reverse rotation of an electric rivet nut tool can be effectively resolved.

  • Publication number: 20160188852
    Abstract: An unlocking method of electronic device includes controlling a display device to display an unlocking interface which includes an input area. Information of one or more input traces is received in response to a series of touch operations applied to the input area. Shapes of the one or more input traces are determined, and whether the shapes of the one or more input traces match predetermined shapes of multiple preset traces which are pre-stored in a storage device. The electronic device is unlocked if the shapes of the one or more input traces match the predetermined shapes of the multiple preset traces.
