Patent number: 8478798Abstract: One embodiment provides a system that facilitates the execution of a web application. During operation, the system allocates a storage space on one or more storage devices for use by the web application. Next, the system creates, for the web application, a private filesystem comprising a private root directory within the storage space. Finally, the system enables access to the private filesystem for the web application through the private root directory in a manner that does not allow access to a host filesystem associated with the one or more storage devices from the web application.Type: GrantFiled: April 21, 2009Date of Patent: July 2, 2013Assignee: Google Inc.Inventors: Eric J. Uhrhane, Matthew Papakipos

Patent number: 8464038Abstract: Methods and apparatus for implementing modes of operation of computing device are disclosed. An example apparatus includes a mode-selection input device having a first state and a second state. The example apparatus also includes firmware operably coupled with the mode-selection input device. In the example apparatus, when the mode-selection input device is in the first state, the firmware is configured to cause the computing device to operate in a first mode of operation, a user mode. In the example apparatus, when the mode-selection input device is in the second state, the firmware is configured to cause the computing device to operate in second mode of operation, a developer mode.Type: GrantFiled: March 10, 2010Date of Patent: June 11, 2013Assignee: Google Inc.Inventors: Randall R.

Publication number: 20130120418Abstract: Some embodiments of the present invention provide a system that renders graphics in a computing system that includes a plugin associated with a web browser in the computing system and a web application configured to execute in the web browser. During operation, the web application specifies a graphics model and provides the graphics model to the plugin. Next, the plugin generates a graphics-processing unit (GPU) command stream from the graphics model. Finally, the plugin sends the GPU command stream to a GPU of the computing system, which renders an image corresponding to the graphics model.Type: ApplicationFiled: January 3, 2013Publication date: May 16, 2013Inventors: Robin Green, Matthew Papakipos, Evangelos Kokkevis, Gregg Tavares

Patent number: 8424082Abstract: A system that safely executes a native code module on a computing device. During operation, the system receives the native code module, which is comprised of untrusted native program code expressed using native instructions in the instruction set architecture associated with the computing device. The system then loads the native code module into a secure runtime environment, and proceeds to execute a set of instructions from the native code module in the secure runtime environment. The secure runtime environment enforces code integrity, control-flow integrity, and data integrity for the native code module. Furthermore, the secure runtime environment moderates which resources can be accessed by the native code module on the computing device and/or how these resources can be accessed. By executing the native code module in the secure runtime environment, the system facilitates achieving native code performance for untrusted program code without a significant risk of unwanted side effects.Type: GrantFiled: May 8, 2008Date of Patent: April 16, 2013Assignee: Google Inc.Inventors: J. Bradley Chen, Matthew T. Harren, Matthew Papakipos, David C. Sehr, Bennet S. Yee, Gregory Dardyk

Publication number: 20090282477Abstract: A system that validates a native code module. During operation, the system receives a native code module comprised of untrusted native program code. The system validates the native code module by: (1) determining that code in the native code module does not include any restricted instructions and/or does not access restricted features of a computing device; and (2) determining that the instructions in the native code module are aligned along byte boundaries such that a specified set of byte boundaries always contain a valid instruction and control flow instructions have valid targets. The system allows successfully-validated native code modules to execute, and rejects native code modules that fail validation. By validating the native code module, the system facilitates safely executing the native code module in the secure runtime environment on the computing device, thereby achieving native code performance for untrusted program binaries without significant risk of unwanted side effects.Type: ApplicationFiled: May 8, 2008Publication date: November 12, 2009Applicant: Google Inc.Inventors: J.

Patent number: 7075539Abstract: A computing system has a graphics processor, a graphics memory, main memory, a bridge, and a central processing unit configured to process floating-point data of a first fixed size. An interconnect grid includes communication paths to link the graphics processor, the graphics memory, main memory, the bridge, and the central processing unit. A computing system component (e.g., the graphics processor or central processing unit) converts floating-point data to graphics floating-point data with a fixed size smaller than the fixed size of the floating-point data. The computing system passes the floating-point data and/or the graphics floating-point data over at least a portion of the interconnect grid. Alternately, the graphics processor may directly read and process previously compressed and stored graphics floating-point data.Type: GrantFiled: May 30, 2003Date of Patent: July 11, 2006Assignee: NVIDIA CorporationInventors: Steven Gregory Foster, Jr., Thomas H.
