Patent number: 7511718Abstract: A media integration layer including an application programming interface (API) and an object model allows program code developers to interface in a consistent manner with a scene graph data structure in order to output graphics. Via the interfaces, program code adds child visuals to other visuals to build up a hierarchical scene graph, writes Instruction Lists such as geometry data, image data, animation data and other data for output, and may specify transform, clipping and opacity properties on visuals. The media integration layer and API enable programmers to accomplish composition effects within their applications in a straightforward manner, while leveraging the graphics processing unit in a manner that does not adversely impact normal application performance. A multiple-level system includes the ability to combine different media types (such as 2D, 3D, Video, Audio, text and imaging) and animate them smoothly and seamlessly.Type: GrantFiled: October 23, 2003Date of Patent: March 31, 2009Assignee: Microsoft CorporationInventors: Sriram Subramanian, Leonardo E. Blanco, Donald B. Curtis, Joseph S. Beda, Gerhard A. Schneider, Greg D. Schechter, Adam M. Smith, Eric S. Vandenberg, Matthew W. Calkins, Kevin T. Gallo, Michael Stokes, Rajat Goel

Patent number: 7502516Abstract: An improved system and method for an extensible codec architecture for digital images is provided. Executable software code may be operably coupled to a codec manager for requesting imaging operations to be performed on a digital image. The codec manager may receive the request to perform an imaging operation on the digital image and may select an imaging component, such as a codec, from one or more imaging components registered in the computer system for performing an imaging operation on the digital image. An arbitration manager may include functionality for requesting enumeration of the operations an imaging component may perform on a particular digital image. One or more pixel format converters may then convert the pixel format in the digital image to a pixel format supported by an imaging component installed on the system.Type: GrantFiled: February 17, 2005Date of Patent: March 10, 2009Assignee: Microsoft CorporationInventors: David Albert, Frank Alva Krueger, Rajat Goel, Peter A.

Patent number: 7373486Abstract: In one embodiment, a renamer comprises a plurality of storage locations and compare circuitry. Each storage location is assigned to a respective renameable resource and is configured to store an identifier corresponding to a youngest instruction operation that writes the respective renameable resource. Coupled to receive an input representing one or more retiring instruction identifiers corresponding to instruction operations that are being retired, the compare circuitry is configured to detect a match between at least a first identifier in a first storage location and one of the retiring identifiers. An encoded form of the identifiers is logically divided into a plurality of fields, and the input comprises a first plurality of bit vectors. Each of the first plurality of bit vectors corresponds to a respective field and includes a bit position for each possible value of the respective field.Type: GrantFiled: August 29, 2005Date of Patent: May 13, 2008Assignee: P.A.

Publication number: 20080008392Abstract: Various embodiments are disclosed relating to providing multiple and native representations of an image. According to an example embodiment, multiple realizations of an image may be generated and provided, rather than only a single realization, for example. Also, in another embodiment, the generation and output of multiple realizations may use one or more native objects to natively perform the transforms or image processing to provide the images or realizations.Type: ApplicationFiled: July 7, 2006Publication date: January 10, 2008Applicant: Microsoft CorporationInventors: Rajat Goel, Margaret L. Goodwin, Radu C. Margarint, Robert A. Wlodarczyk, Thomas W. Olsen, Wei-Chung Jones Wang

Publication number: 20070052732Abstract: In aspects, a class hierarchy is defined that provides definitions of methods for operating on at least bitmaps and vector graphics. A software developer may instantiate an object according to a class definition of the class hierarchy and assign it to any variable (e.g., a control's property) having a type of an ancestor class of the class. The object may be associated with an image internally represented as bitmap, vector graphics, or some other representation. The control does not need to be aware of how the image is represented. Rather, to draw an image associated with the object, a draw method associated with the object may be called.Type: ApplicationFiled: August 1, 2005Publication date: March 8, 2007Applicant: Microsoft CorporationInventors: Greg Schechter, Adam Smith, Leonardo Blanco, Sriram Subramanian, Rajat Goel

Publication number: 20060184808Abstract: An integrated circuit includes multiple power domains. Supply current switch circuits (SCSCs) are distributed across each power domain. When a signal is present on a control node within a SCSC, the SCSC couples a local supply bus of the power domain to a global supply bus. An enable signal path extends through the SCSCs so that an enable signal can be propagated down a chain of SCSCs from control node to control node, thereby turning the SCSCs on one by one. When the domain is to be powered up, a control circuit asserts an enable signal that propagates down a first chain of SCSCs. After a programmable amount of time, the control circuit asserts a second enable signal that propagates down a second chain. By spreading the turning on of SCSCs over time, large currents that would otherwise be associated with coupling the local and global buses together are avoided.Type: ApplicationFiled: September 16, 2005Publication date: August 17, 2006Inventors: Lew Chua-Eoan, Matthew Severson, Sorin Dobre, Tsvetornir Petrov, Rajat Goel
