20080288719 | Memory Tracing in an Emulation Environment - A system and method are disclosed to trace memory in a hardware emulator. In one aspect, a first Random Access Memory is used to store data associated with a user design during emulation. At any desired point in time, the contents of the first Random Access Memory are captured in a second Random Access Memory. After the capturing, the contents of the second Random Access Memory are copied to a visibility system. During the copying, the user design may modify the data in the first Random Access Memory while the captured contents within the second Random Access Memory remain unmodifiable so that the captured contents are not compromised. In another aspect, different size memories are in the emulator to emulate the user model. Larger memories have their ports monitored to reconstruct the contents of the memories, while smaller memories are captured in a snapshot RAM. Together the two different modes of tracing memory are used to provide visibility to the user of the entire user memory. | 11-20-2008 |
20090259457 | Trace Routing Network - Hardware emulation produces relevant and irrelevant trace data. Verification of a design under test requires knowledge of the relevant trace data. Data lines are provided to capture trace data from the hardware emulator's logic elements during emulation. The data lines connect the outputs of these logic elements to the inputs of a configurable interconnect circuit. The configurable interconnect circuit is capable of being programmed to select from a plurality of these inputs to connect a number of the data lines to a scan chain or trace data storage circuit. The configurable interconnect circuit can then selectively connect those data lines carrying relevant trace data to a trace data processing circuit. The trace data processing circuit may be a scan chain, analysis device or storage device or other suitable trace data processing device. | 10-15-2009 |

20080303839 | Facilitating caching in an image-processing system - Embodiments of the present invention provide a system for performing caching in an image-processing system. The system starts by receiving a filtering query for resources in a cache. The system then returning a subcache in response to the filtering query. Upon receiving a resource query for resources in the subcache, the system performs the filtering query on the cache, populates the subcache with addresses of resources returned by the filtering query until the resource query is satisfied, and returns available resources from the subcache in response to the resource query. | 12-11-2008 |
20080304770 | Method and apparatus for managing image-processing operations - Embodiments of the present invention provide a system for performing image conversion operations. The system starts by receiving a request from a client for one or more pixel buffers containing a pixel-formatted, cropped, geometrically transformed, and/or color matched version of an image representation. The system then determines if a provider can provide the one or more pixel buffers. If so, the system calls the provider to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation. Otherwise, the system calls the provider to generate one or more intermediate pixel buffers, generates a sequence of converters for converting the one or more intermediate pixel buffers, and calls the sequence of converters to generate the one or more pixel buffers containing the pixel-formatted, cropped, geometrically transformed, and/or color matched version of the image representation. | 12-11-2008 |
20090153474 | Motion Tracking User Interface - A method to transition focus of a display corresponding to an object's motion tracked by a video camera or like device is disclosed. In one implementation, the display shows one or more windows or user interfaces on the display. The object's motion can be used to select one of the windows or user interfaces on the display and manipulate content presented in the window or user interface. In another implementations, the object's motion can manipulate a three-dimensional graphical icon in a three-dimensional display environment, for example, by rotating it. In another implementation, the method further tracks motion of a second object and shifts focus of the display corresponding to the motion of the second object. In another implementation, a second display may be added to mirror the focus transition corresponding to the object's motion. | 06-18-2009 |
20090153648 | THREE-DIMENSIONAL MOVIE BROWSER OR EDITOR - A three-dimensional movie browser or editor is disclosed. In one aspect, video frames are quads in space. A movie plays at full quality by moving the quads in space at a speed of the movie and having a camera follow the quads. A focus frame in the movie is put forward by a cover-flow/dock like expansion around it. Video frames are loaded at a resolution and with an interval that depends on their position regarding a focus point or the optical flow between the frames. | 06-18-2009 |
20100306651 | METHOD FOR CREATING, EXPORTING, SHARING, AND INSTALLING GRAPHICS FUNCTIONAL BLOCKS - Systems, apparatuses, computer readable media, and methods for creating, exporting, sharing, and installing graphics functional blocks are described herein. In one embodiment, a selection is received from a graphical user interface (GUI) for one or more patches of multiple linked patches representing a graphics composition. In response to the selection, a dependency analysis is performed to determine one or more related patches that have a dependency relationship with the selected patches. Based on the dependency analysis, source code associated with the selected patches and the related patches is extracted without extracting source code of unselected and unrelated patches. Thereafter, the selected patches, the related patches, and the extracted source code are exported into a composition file to be shared with another user. Other methods and apparatuses are also described. | 12-02-2010 |
20100306680 | FRAMEWORK FOR DESIGNING PHYSICS-BASED GRAPHICAL USER INTERFACE - A graphics development framework for designing physics-based graphical user interfaces is described herein. According to one embodiment, visually linkable patches are displayed in a first window of a graphics development framework, where the patches represent a graphics composition which when rendered, animate a physical movement of a graphics object of the physics-based GUI. A feedback patch is displayed to visually provide a feedback from an output of the composition to an input of the composition, such that a subsequent physical movement of the graphics object is determined based on a previous physical movement of the graphics object, without requiring a user to program source code of the displayed patches. A result of rendering is instantly displayed in a second window of the graphics development framework, simulating the physical movement of the graphical object. Other methods and apparatuses are also described. | 12-02-2010 |
