A method for rendering content includes initiating a rasterization of a complete version of webpage content, the webpage content including a set of webpage elements, and setting an original tile pixel resolution of the set of webpage elements to be the same as a screen pixel resolution of a display on a content display device. The method includes rasterizing the set of webpage elements at a lower tile resolution onto a tile buffer, the lower tile pixel resolution differing from the original tile pixel resolution by a scaling factor. The method includes scaling up the set of webpage elements rasterized at the lower tile pixel resolution to the screen pixel resolution of the display. Finally, the method includes compositing the rasterized set of webpage elements onto a display during the rasterization of the complete version of the webpage content, and then compositing the complete version of the webpage content.

Power optimization by rendering low-resolution tiles during page load

Unlike the GPU's FlexRender, a browser engine can intercept rendering at a higher level in the software stack, and because of the simpler nature of the browser tiles that need to be rendered, a browser engine can instruct the GPU to perform composition via traditional tiled-rendering or via direct rendering, where an output of the GPU is written to slower system memory, rather than the faster GPU memory.

Efficient browser composition for tiled-rendering graphics processing units

Provided is a method for pausing activities in an internet browser in which a plurality of webpages are open, at least one of the webpages being a background webpage relative to at least one other of the webpages. The method may comprise executing, while the plurality of webpages are open, software scripts on the background webpage. The method may then include analyzing a Document Object Model (DOM) and a rendering tree of a background webpage to discover what software scripts the background webpage runs while in the background, and determining whether the background webpage provides title bar updates. The method may also include periodically pausing, by a background activity suspension component, the execution of the software scripts for a pause duration to conserve power or processing resources, and adjusting the pause duration to be longer or shorter based on characteristics of the software scripts that run on the background webpage.

Systems, methods, and apparatus are herein disclosed for controlling a display brightness based on user action or user interest in the display. In particular, the display brightness can be dimmed upon identification of a first marker indicative of a user action such as a request for a webpage. The brightness of the display can be increased or returned to its original state upon identification of a second marker indicative of completion of a user equipment activity triggered by the user action. In some embodiments, another brightness state between these two can be used as an intermediary and is triggered when a third marker, indicative of a progression of the user equipment activity, is identified.

Systems, methods, and apparatus are herein disclosed for prefetching node data of a linked data structure into a processor's cache so as to decrease linked data structure traversal latency. In particular, as the linked data structure is created or modified, forward and reverse prefetch nodes are identified and links identifying locations of these nodes are written to nodes that will be traversed N nodes prior to the prefetch nodes. Once the linked data structure has been created, traversals of the structure use the prefetch links to prefetch node data into the processor cache, so that when traversal reaches a node, that node's data is read from processor cache rather than from memory.

Systems, methods, and apparatus are disclosed for conserving battery power in a user equipment (UE) by idling the modem when it is not needed in an active state. Idling can occur (1) between a user request for content and the start of the content download; (2) after the content download; and (3) after additional dynamic content has been downloaded, further scripting has finished, or UE data has been uploaded to the network, but before another user request for content has been made. Grace timers can be used before the second and third opportunities to ensure that the modem is not idled while still in use, but also to minimize the time that the modem is in an active state but not being used. These timers can be fixed or dynamic and their duration based on historical trends or testing of particular content or content types.

This disclosure describes systems, methods, and apparatus for reducing power consumption of an application processor in a user equipment. State information of applications that indicate an expected load requirement that the applications will likely place on the application processor, can be used to control power management features of the application processor. For instance, an operating frequency of the application processor, or online cores of the application processor, can be reduced. The number of online cores (those that are not idled) can also be changed to tailor performance and power consumption to the load requirement. Other power management techniques such as adjusting core operational voltage can also be implemented.

Frequency reduction of mobile device cores based on application processing requirements

Methods and apparatus for processing scripting-language code in webpages are disclosed. The method includes obtaining scripting-language code that is utilized by a higher-priority webpage, compiling the scripting-language code to generate higher-priority compiled code objects, storing the higher-priority compiled code objects on a communication device, distinguishing the higher-priority compiled code objects from other compiled code objects that are stored on the communication device to delay the higher-priority compiled code objects from being removed from the communication device, and executing the higher-priority compiled code objects when the webpage is requested by the user. In many variations, this approach is not applied to all webpages visited, but only on certain webpages and scripts that are considered high priority, either implicitly or explicitly, based on a priority function that computes a multi-level priority from the history and past browser activity.

A mobile computing device comprising memory components, a wireless transmitter/receiver, and one or more applications. The mobile computing device utilizes HTTP via the wireless transmitter/receiver to request and receive information from a remote device, wherein the information is to be used by the one or more applications. However, an Accept-Encoding header is not sent with a HTTP GET request when the information comprises one of, an image, audio, video, and flash data.

Request packet size reduction

A computing device comprising an application utilizing content comprising a plurality of JavaScripts, wherein the computing device compiles and executes a first of the plurality of JavaScripts substantially simultaneously as compiling and executing a second of the plurality of JavaScripts.
