Publication number: 20120306900Abstract: Techniques for hardware accelerated caret rendering are described in which a system based caret is emulated using hardware acceleration technology. The hardware accelerated caret can be rendered using dedicated graphics processing hardware to look and feel like a system caret. This can involve using pixel shaders to produce the hardware accelerated caret and a employing a back-up texture to remove the caret after it is drawn and cause the caret to blink. In addition, rendering of the caret can be coordinated with other animations and/or other presentations of a frame buffer to piggy back drawing of the caret onto other drawing operations. This can reduce the number of times the frame buffer is presented and therefore improve performance.Type: ApplicationFiled: June 14, 2012Publication date: December 6, 2012Applicant: Microsoft CorporationInventors: Rafael V. Cintron, Richard K. James, Benjamin C. Constable, Cenk Ergan

Publication number: 20120290785Abstract: In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.Type: ApplicationFiled: July 23, 2012Publication date: November 15, 2012Applicant: Microsoft CorporationInventors: Cenk Ergan, Clark D.

Publication number: 20120274645Abstract: An event, such as a vertical blank interrupt or signal, received from a display adapter in a system is identified. Activation of a timer-driven animation routine that updates a state of an animation and activation of a paint controller module that identifies updates to the state of the animation and composes a frame that includes the updates to the state of the animation are aligned, both being activated based on the identified event in the system.Type: ApplicationFiled: July 6, 2012Publication date: November 1, 2012Applicant: Microsoft CorporationInventors: Cenk Ergan, Benjamin C.

Publication number: 20120216217Abstract: One or more application programming interfaces (APIs) are exposed by a host program running on a device to facilitate a control program displaying content in a window in which the host program displays content. As part of an API, a method is exposed that the control program can invoke to pass to the host program a definition of a surface presenter to be created by the host program. Additionally, the control program can store content that the control program desires to have presented in a buffer of the surface presenter, and invoke another method exposed as part of an API to pass to the host program an indication of the content that the control program desires to have displayed in the window in which the host program displays content.Type: ApplicationFiled: February 22, 2011Publication date: August 23, 2012Applicant: MICROSOFT CORPORATIONInventors: Benjamin C.

Publication number: 20120183233Abstract: In one or more embodiments, a framework is provided in which image decoding can be delayed based on heuristics, and later initiated based on a use type associated with the image or the likelihood that the image is going to be used. For example, a use history and priority system can enable images that are currently being rendered and/or are likely to get rendered to be decoded before images that have a history of being downloaded but never used. Accordingly, by decoupling image download from image decoding, CPU resources and memory can be more efficiently utilized.Type: ApplicationFiled: January 19, 2011Publication date: July 19, 2012Applicant: MICROSOFT CORPORATIONInventors: Cenk Ergan, Rafael V.

Publication number: 20120173824Abstract: Embodiments of the invention provide techniques for managing cache metadata providing a mapping between addresses on a storage medium (e.g., disk storage) and corresponding addresses on a cache device at which data items are stored. In some embodiments, cache metadata may be stored in a hierarchical data structure comprising a plurality of hierarchy levels. When a reboot of the computer is initiated, only a subset of the plurality of hierarchy levels may be loaded to memory, thereby expediting the process of restoring the cache metadata and thus startup operations. Startup may be further expedited by using cache metadata to perform operations associated with reboot.Type: ApplicationFiled: February 2, 2012Publication date: July 5, 2012Applicant: Microsoft CorporationInventors: Mehmet Iyigun, Yevgeniy Bak, Michael Fortin, David Fields, Cenk Ergan, Alexander Kirshenbaum

Publication number: 20110276743Abstract: The invention is directed towards a system and method that utilizes external memory devices to cache sectors from a rotating storage device (e.g., a hard drive) to improve system performance. When an external memory device (EMD) is plugged into the computing device or onto a network in which the computing device is connected, the system recognizes the EMD and populates the EMD with disk sectors. The system routes I/O read requests directed to the disk sector to the EMD cache instead of the actual disk sector. The use of EMDs increases performance and productivity on the computing device systems for a fraction of the cost of adding memory to the computing device.Type: ApplicationFiled: July 21, 2011Publication date: November 10, 2011Applicant: MICROSOFT CORPORATIONInventors: Alexander Kirshenbaum, Cenk Ergan, Michael R.
