Patent number: 8762940Abstract: The invention described herein includes a system, method, and computer program product for adding functionality to an application program. The invention includes a tool which can be used in conjunction with any of a plurality of application programs. The tool can be represented to a user by a tool icon on a desktop. After creating or opening a file or other object with an application program, the user can drag and drop a tool icon representing the tool into the application window. This allows the tool program to operate on the object. A windowing system event handler receives information from a user interface regarding the dragging and dropping of the tool icon. The fact that the tool icon has been dragged and dropped into the application window is reported by the windowing system event handler to a base module. The base module mediates communication between the tool program and the application program.Type: GrantFiled: August 30, 2006Date of Patent: June 24, 2014Assignee: ATI Technologies Inc.Inventor: Mark Grossman

Patent number: 8738856Abstract: A system and methods are shown for handling multiple target memory requests. Memory read requests generated by a peripheral component interconnect (PCI) client are received by a PCI bus controller. The PCI bus controller passes the memory request to a memory controller used to access main memory. The memory controller passes the memory request to a bus interface unit used to access cache memory and a processor. The bus interface unit determines if cache memory can be used to provide the data associated with the PCI client's memory request. While the bus interface unit determines if cache memory may be used, the memory controller continues to process the memory request to main memory. If cache memory can be used, the bus interface unit provides the data to the PCI client and sends a notification to the memory controller.Type: GrantFiled: April 24, 2007Date of Patent: May 27, 2014Assignee: ATI Technologies, Inc.Inventors: Michael Frank, Santiago Fernandez-Gomez, Robert W.

Patent number: 8677416Abstract: A method, system, and software for improved display of multiple media channels are disclosed herein. A system may be used to select, independent of direct user input, a subset of a plurality of media channels based on a user's viewing pattern. The system can include one or more media sources, a media processing system, and a display device, as well as a method for its use. The media processing system receives a plurality of media channels from the one or more media sources. One or more attributes associated with each media channel are compared with a user's viewing pattern determined independent of direct user input by the media processing system. A surf list is generated from the plurality of media channels, where the surf list includes a subset of the plurality of media channels having one or more attributes that are congruent with the user's viewing pattern.

Patent number: 8345756Abstract: Embodiments of a method and system for intra-prediction in decoding video data are described herein. In various embodiments, a high-compression-ratio codec (such as H.264) is part of the encoding scheme for the video data. Embodiments pre-process control maps that were generated from encoded video data, and generating intermediate control maps comprising information regarding decoding the video data. The control maps indicate which units of video data in a frame are to be processed using an intra-prediction operation. In an embodiment, intra-prediction is performed on a frame basis such that intra-prediction is performed on an entire frame at one time. In other embodiments, processing of different frames is interleaved. Embodiments increase the efficiency of the intra-prediction such as to allow decoding of high-compression-ratio encoded video data on personal computers or comparable equipment without special, additional decoding hardware.Type: GrantFiled: August 31, 2006Date of Patent: January 1, 2013Assignee: ATI Technologies, Inc.Inventors: Alexander Lyashevsky, Jason Yang, Arcot J.

Publication number: 20120274655Abstract: A system and method for improved antialiasing in video processing is described herein. Embodiments include multiple video processors (VPUs) in a system. Each VPU performs some combination of pixel sampling and pixel center sampling (also referred to as multisampling and supersampling). Each VPU performs sampling on the same pixels or pixel centers, but each VPU creates samples positioned differently from the other VPUs corresponding samples. The VPUs each output frame data that has been multisampled and/or supersampled into a compositor that composites the frame data to produce an antialiased rendered frame. The antialiased rendered frame has an effectively doubled antialiasing factor.Type: ApplicationFiled: July 2, 2012Publication date: November 1, 2012Applicant: ATI Technologies, Inc.Inventors: Arcot J.

Patent number: 8281183Abstract: An apparatus with circuit redundancy includes a set of parallel arithmetic logic units (ALUs), a redundant parallel ALU, input data shifting logic that is coupled to the set of parallel ALUs and that is operatively coupled to the redundant parallel ALU. The input data shifting logic shifts input data for a defective ALU, in a first direction, to a neighboring ALU in the set. When the neighboring ALU is the last or end ALU in the set, the shifting logic continues to shift the input data for the end ALU that is not defective, to the redundant parallel ALU. The redundant parallel ALU then operates for the defective ALU. Output data shifting logic is coupled to an output of the parallel redundant ALU and all other ALU outputs to shift the output data in a second and opposite direction than the input shifting logic, to realign output of data for continued processing, including for storage or for further processing by other circuitry.Type: GrantFiled: July 27, 2009Date of Patent: October 2, 2012Assignee: ATI Technologies Inc.Inventors: Michael Mantor, Ralph Clayton Taylor, Robert Scott Hartog

Patent number: 8275972Abstract: In various embodiments, dedicated mask pins are eliminated by sending a data mask on address lines of the interface. A memory controller receives a request for a memory write operation from a memory client and determines the granularity of the write data from a write data mask sent by the client. Granularity, as used herein, indicates a quantity of write data to which each bit of the received write data mask applies. In an embodiment, the memory controller generates a particular write command and a particular write data mask based on the granularity of the write data. The write command generated is typically the most efficient of several write commands available, but embodiments are not so limited. The write command is transmitted on command lines of the interface, and the write data mask is transmitted on address lines of the interface.Type: GrantFiled: August 23, 2006Date of Patent: September 25, 2012Assignee: ATI Technologies, Inc.Inventors: Xiaoling Xu, Warren F.

Patent number: 8248536Abstract: The invention provides techniques for separating luma and chroma signal components in a composite SECAM video signal. During reception, the SECAM video signal is split into luma and chroma output. The amplitude of the chroma carrier is monitored during reception. If the chroma carrier amplitude is greater than a threshold, the value of the chroma output can be reduced. Also, if the chroma carrier amplitude is greater than another threshold, a portion of the chroma carrier can be added to the luma; or the trap band of the band-trap filter for extracting luma from the composite video can be reduced. The respective amount of the reduction in the chroma output and the increase in the luma output are independently determined but both may proportional to the magnitude of the deviation in the chroma carrier amplitude from the different thresholds.Type: GrantFiled: April 7, 2006Date of Patent: August 21, 2012Assignee: ATI Technologies, Inc.Inventors: Dongsheng Wu, Robert B.
