A method and system for performing domain name service (DNS) pre-fetching, content pre-fetching, or a combination thereof, are disclosed for a wireless portable computing device (PCD). The system and method may include rendering a web page on a display screen of the PCD and performing a DNS pre-fetch for any visible links within the web page. Further, the method may include determining whether a screen changing operation (i.e., a scrolling operation) is being performed and placing one or more DNS pre-fetch tasks in a queue for each link that is displayed on the display screen when the screen changing operation is performed. The method and system may reduce wait times for a wireless PCD when it is rendering webpages on its display screen.

Methods and apparatus are presented for H-ARQ process dynamic memory management. A method for dynamically managing memory for storing data associated with H-ARQ processes is presented, which includes receiving a packet associated with a H-ARQ process, determining if a free memory location is available in a H-ARQ buffer, assigning the packet to the free memory location, determining if the packet was successfully decoded, and retaining the packet in the assigned memory location for combination with a subsequent packet retransmission if the packet was not successfully decoded. Also presented are apparatus having logic configured to perform the presented methods.

Methods and apparatus for H-ARQ process memory management

Methods and apparatuses are provided for managing a performance level of a processing circuit, such as a modem, by making adjustments to one or more operating parameters provided to the processing circuit, such as a voltage supplied to the processing circuit and/or a clock frequency of the processing circuit. The processing circuit is adapted to monitor wireless wide area network (WWAN) protocol information. The processing circuit may adjust at least one operating parameter provided to the processing circuit in response to the monitored wireless wide area network (WWAN) protocol information.

Using wireless wide area network protocol information for managing a performance level of a processor

A method of establishing transmission control protocol (TCP) connections is disclosed and may include receiving a uniform resource locator (URL) as part of a hyper text transfer protocol (HTTP) request. Further, the method may include searching a host database with the URL and determining whether host data for the URL is available. The method may also include performing a domain name service (DNS) lookup for a URL host and for one or more sub-resource hosts, wherein all DNS lookups are performed in parallel at substantially the same time, when host data for the URL is available.

System and method of establishing transmission control protocol connections

Systems and methods for wireless communications are provided. These include data deciphering components, interrupt processing components, adaptive aggregations methods, optimized data path processing, buffer pool processing, application processing where data is formatted in a suitable format for a destination process, and Keystream bank processing among other hardware acceleration features. Such systems and methods are provided to simplify logic designs and mitigate processing steps during wireless network data processing.

Hardware acceleration for WWAN technologies

A method for handling out-of-synchronization (SYNC) includes generating a plurality of combination sets of transport channels utilized by a communication device. The method also includes selecting, based on a window-based parameter, a highest-ranking combination set of transport channels out of the plurality of combination sets of transport channels. The highest-ranking combination set of transport channels excludes one or more out-of-SYNC transport channels. The method further comprises providing, to a window-based data processing unit, data packets from transport channels in the highest-ranking combination set of transport channels, without providing data packets from the one or more out-of-SYNC transport channels to the window-based data processing unit. Apparatus and machine-readable media for out-of-SYNC avoidance and/or detection are also provided.

Out-of-synchronization handling method and apparatus

Systems and methodologies are described that facilitate enhanced data service functionality for data services operating in a multi-processor computing environment. As described herein, respective processors and/or other components can be utilized to form a Smart Peripheral Subsystem (SPS). As further described herein, the SPS can operate in association with a modem processor and an application processor at a mobile computing device in order to reduce loading at the application processor and improve memory usage efficiency. In the case of a mobile computing device sharing a network connection with a tethered computing device, the SPS can couple a modem interface associated with the mobile computing device and an interface through which the disparate computing device is tethered to the mobile computing device such that operations such as Layer 2 (L2) framing and/or de-framing, Network Address Translation (NAT), or the like can be offloaded to the SPS under various circumstances.

Method and apparatus for managing data services in a multi-processor computing environment

A method and system for managing one or more memory resources of a wireless handheld computing device is described. The method and system may include receiving a request to initiate a web browser module and receiving input for a web address. The method and system may also include receiving a file corresponding to the web address and reviewing one or more objects present within the file. The method and system may determine if an object already exists in the one or more memory resources. And if the object does not exist in the one or more memory resources, then the method and system may calculate a priority for the object. The priority of the object may then be assigned and stored. It may also be determined if the current object will exceed the threshold of the one or more memory resources, and discarding other objects with lower priority as needed.
