Abstract: 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.

Abstract: Methods, systems and devices for generating data models in a client-cloud communication system may include applying machine learning techniques to generate a first family of classifier models that describe a cloud corpus of behavior vectors. Such vectors may be analyzed to identify factors in the first family of classifier models that have the highest probability of enabling a mobile device to better determine whether a mobile device behavior is malicious or benign. Based on this analysis, a second family of classifier models may be generated that identify significantly fewer factors and data points as being relevant for enabling the mobile device to better determine whether the mobile device behavior is malicious or benign based on the determined factors. A mobile device classifier module based on the second family of classifier models may be generated and made available for download by mobile devices, including devices contributing behavior vectors.

Abstract: A digital rights management system includes an authentication module and a decryption module. If desired, the modules can be implemented in separate integrated circuits. The authentication module retrieves authentication information for protected content and powers down after the authentication information is retrieved. The decryption module decrypts the protected content based on the authentication information while the authentication module is powered down.

Abstract: A system, methods and server for creating and using manifests to support the rendering of a webpage by a computing device. Multiple computing devices may render a webpage and generate meta data. A server may collect and use the meta data to generate a manifest. The manifest may provide information describing priorities and formats for loading the resources of the webpage. The computing device may transmit information to the server for comparison with the manifest and to determine priorities and formats for retrieving the resources of the webpage. The server may request and send the webpage resources to the computing device based on the manifest information, to which the computing device may render the webpage. The server may access the webpage and generate meta data to create the manifest. The server may alternatively send the manifest information to the computing device.

Abstract: 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.

Abstract: Memory access instructions, such as load and store instructions, are processed in a processor-based system. Processor hardware pipeline configurations enable efficient performance of memory access instructions, such as a pipeline configuration that enables, for a memory access operation request by a register-operand based virtual machine, computation of the memory location corresponding to a virtual-machine register by extracting a bit-field from the virtual-machine instruction and accessing (load or store) the computed memory location that represents a virtual register of the virtual-machine, in a single pass through the pipeline. Thus this processor hardware pipeline configuration enables a virtual machine register read/write operation to be performed by a single hardware processor instruction through a single pass in the processor hardware pipeline, for a register-operand based virtual machine.

Abstract: Methods and apparatus for performing efficient pattern matching in a client-server network are described herein. A communication device acquires an object to be matched. At least one reduced set of features is extracted from the object to be matched and a determination as to whether the object to be matched matches one of a plurality of known objects in a local library stored on the communication device is generated. An indication representing a match of the object is presented if the determination indicates a local match exists in the local library. A match request including the at least one reduced set of features is transmitted for a remote matching determination when the determination indicates that no local match exists in the local library. In accordance with some aspects, a series of one or more match requests may be transmitted for a remote matching determination.

Abstract: 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.
