Abstract

A method and computing apparatus for controlling operation of hardware processing components are disclosed. The method may include receiving a data packet (e.g., a media frame) at the computing device, processing the data packet with a plurality of hardware components to display the data packet, and monitoring movement of the data packet among the hardware components. A time indication for each hardware component is generated that indicates when the data packet will be received, and a frequency of each of the hardware components is adjusted based upon when the frame will arrive to be processed.

First claim

What is claimed is:

1 . A method for controlling operation of hardware processing components on a computing device, the method comprising:
receiving a data packet at the computing device; processing the data packet with a plurality of hardware components to display the data packet; monitoring movement of the data packet among the hardware components; generating, based upon the monitoring, time indications, each of the time indications indicating when a corresponding one of the hardware components will receive the data packet; and adjusting a frequency of each of the hardware components based upon when the data packet will be received by each of the hardware components.

2 . The method of claim 1 , including:
initiating an interrupt when an application processor receives the data packet; obtaining type and size information about the data packet; and adjusting the frequency of each of the hardware components based upon the type and size information so that each of the hardware components completes its processing of the data packet within a particular time window.

3 . The method of claim 2 , including:
receiving Vsync signals that define boundaries of the particular time window.

4 . The method of claim 2 , wherein the application processor reads a header of the data packet to obtain the type and size information about the data packet.

5 . The method of claim 1 , wherein the frequency of each of the hardware components is adjusted before the data packet arrives to be processed.

6 . A computing device comprising:
a network interface to receive content; a plurality of hardware components to obtain and process data packets from the content to generate displayable content; a display to display the displayable content; a frame monitor component that is configured to:
receive a data packet at the computing device;
process the data packet with a plurality of hardware components to display the data packet;
monitor movement of the data packet among the hardware components;
generate, based upon the monitoring, time indications that each indicate when a corresponding one of the hardware components will receive the data packet; and
a plurality of clock scaling components, each of the clock scaling components configured to receive a time indication from the frame monitor and scale a frequency of a corresponding one of the plurality of hardware devices.

7 . The computing device of claim 6 , wherein the hardware components include an application processor that initially receives the data packet and generates an interrupt when the data packet is received to inform the frame monitor that the data packet is received.

8 . The computing device of claim 7 , wherein the application processor obtains frame type and frame size information from the data packet and provides the frame size and frame type information to the frame monitor.

9 . The computing device of claim 6 , wherein the frame monitor provides the frame size and type information to at least one of the hardware components.

10 . The computing device of claim 6 , wherein the hardware components include hardware components selected from the group consisting of an application processor, graphics processing unit, mobile display processor, and a digital signal processor.

11 . A non-transitory, tangible processor readable storage medium, encoded with processor readable instructions to perform a method for operating a plurality of hardware components, the method comprising:
receiving a data packet at the computing device; processing the data packet with a plurality of hardware components to display the data packet; monitoring movement of the data packet among the hardware components; generating, based upon the monitoring, time indications that each indicate when a corresponding one of the hardware components will receive the data packet; and adjusting a frequency of each of the hardware components based upon when the frame will arrive to be processed.

12 . The non-transitory, tangible processor readable storage medium of claim 11 , the method including:
initiating an interrupt when an application processor receives the data packet; obtaining type and size information about the data packet; and adjusting the frequency of each of the hardware components based upon the type and size information so that each of the hardware components completes its processing of the data packet within a particular time window.

13 . The non-transitory, tangible processor readable storage medium of claim 12 , the method including:
receiving Vsync signals that define boundaries of the particular time window.

14 . The non-transitory, tangible processor readable storage medium of claim 12 , the method including reading a header of the data packet to obtain the type and size information about the data packet.

15 . The non-transitory, tangible processor readable storage medium of claim 11 , wherein the frequency of each of the hardware components is adjusted before the data packet arrives to be processed.
