  • Publication number: 20220345656
    Abstract: An imaging device includes a controller and a generator. The controller controls an imaging unit on the basis of a command and data received from a host in accordance with an I2C/I3C communication protocol. The generator generates a second control signal indicating whether or not to apply intra-frame dynamic frequency scaling (DFS) or intra-frame dynamic voltage frequency scaling (DVFS) on the basis of a first control signal received from the host via a first route different from the I2C/I3C communication protocol, and outputs the second control signal to the host via a second route different from the I2C/I3C communication protocol.

  • Patent number: 7761748
    Abstract: Methods and apparatus provide for: a plurality of stages of combinational logic, each stage including a full latch circuit operable to transfer data into the given stage of combinational logic and a transparent latch circuit operable transfer output data from the given stage of combinational logic to a next of the stages; in each stage, passing state changes of output data from the given combinational logic irrespective of when such changes occur when a clock signal of the transparent latch circuit is at a first of two logic levels; and in each stage, withholding state changes of the output data until the clock signal of the transparent latch circuit transitions from the second of the two logic levels to the first logic level.

  • Patent number: 7733150
    Abstract: Methods and apparatus for distributing a clock signal to a digital circuit provide for: producing a clock signal; and delaying, advanced, or leaving the clock signal unchanged to produce an output clock signal as a function of a control signal, wherein an amount of delay or advancement between the clock signal and the output clock signal (phase difference) is a function of time variant changes in a magnitude of a power supply voltage to the digital circuit.

  • Patent number: 7676683
    Abstract: Processors arranged in a multi-processor configuration for substantially parallel operations receive their initialization data in order to start operations, such as graphics computations, real-time multimedia streaming, etc. Due to a change in the processing load, one or more processors might be deactivated. Subsequently, the load increases to such a level that requires all or some of the deactivated processors to be active again. In this case, the boot-up process of the entire system is not carried out as it would be time-consuming and wasteful; instead, responsive to a control signal only those processors that were previously in inactive mode are re-initialized by selecting a configuration data supplied by another processor, controller or any other intelligent programmable device.
