  • Publication number: 20080120626
    Abstract: Methods and apparatuses for providing hardware acceleration of a web browser are disclosed. In one embodiment, a method of operating a web browser on a computer system includes analyzing a data stream having a plurality of fragments. The method further includes determining what fragments of the data stream should be rendered for storage into separate backing stores. The method further includes rendering the fragments into raster images intended for hardware acceleration. The method further includes storing the raster images in the backing stores located in a graphics processing unit.

  • Publication number: 20070101146
    Abstract: A cryptographic hash of content (e.g., applications, documents, widgets, software, music, videos, etc.) is created and made available for distribution over a network (or by other means) as part of a ticket file. The ticket file can be cryptographically signed to ensure its authenticity. The ticket file and content can be downloaded separately (e.g., from different websites) to a user system (e.g., a computer, mobile phone, media player/recorder, personal digital assistant (PDA), etc.). The user system verifies the signature of the ticket file and the content hash to ensure that the content has not been compromised. The ticket file can include information relating to downloading the content (e.g., a Uniform Resource Identifier (URI)) and other meta-data (e.g., hash type, content information, public key, size, version, etc.).

  • Publication number: 20050283765
    Abstract: A system, method, and computer program for analyzing code execution and software performance characteristics are disclosed. Samples of code during run-time can be displayed as both a top-down tree of calls from a particular function and a bottom-up tree of calls to the particular function. Data mining techniques, including filtering and focusing, remove code that is not of interest and display code that is more relevant to performance analysis. In particular, functions contained in libraries such as system libraries can be stripped from view. The cost associated with an excluded function can be propagated to a calling function, in either the top-down or bottom-up tree. The principles of the present invention can find particular usefulness with respect to analyzing crashlogs.
