  • Patent number: 7882292
    Abstract: An arbiter decides to grant access from multiple clients to a shared resource (e.g. memory) using efficiency and/or urgency terms. Urgency for a client may be determined based on an “in-band” request identifier transmitted from the client to the resource along with the request, and an “out-of-band” request identifier that is buffered by the client. A difference between the out-of-band request identifier and the in-band request identifier indicates the location of the request in the client buffer. A small difference indicates that the request is near the end of the buffer (high urgency), and a large difference indicates that the request is far back in the buffer (low urgency). Efficiency terms include metrics on resource overhead, such as time needed to switch between reading/writing data from/to memory via a shared memory bus, or bank management overhead such as time for switching between DRAM banks.

  • Patent number: 7880743
    Abstract: An improved attribute determination process allows the sharpness of a surface attribute function to be adjusted on a per-object, per-surface, per-texture, per-function, or other appropriate basis. A computer-based animator then can selectively adjust the sharpness or other attribute(s) of portions of a to-be-rendered image without significantly increasing the rendering time. For a selected texture, corresponding sampling regions will be shifted about the respective surface points projected in texture space. A multi-dimensional set of sub-regions can be generated for the shifted sampling region. Bounding boxes can be determined for each sub-region, the boxes occupying less area, such as in texture space, than a single bounding box for the original sampling region. The bounding boxes can be used for local attribute determinations (such as texture lookups) for each sub-region, with the local attributes being processed to determine an attribute for the respective surface point.

  • Patent number: 7882296
    Abstract: Circuits, apparatus, and methods for avoiding deadlock conditions in a bus fabric. One exemplary embodiment provides an address decoder for determining whether a received posted request is a peer-to-peer request. If it is, the posted request is sent as a non-posted request. A limit on the number of pending non-posted requests is maintained and not exceed, such that deadlock is avoided. Another exemplary embodiment provides an arbiter that tracks a number of pending posted requests. When the number pending posted requests reaches a predetermined or programmable level, a Block Peer-to-Peer signal is sent to the arbiter's clients, again avoiding deadlock.

  • Patent number: 7879066
    Abstract: A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.

  • Patent number: 7877999
    Abstract: A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.

  • Patent number: 7879729
    Abstract: In a method of forming micro patterns of a semiconductor device, first etch mask patterns are formed over a semiconductor substrate. An auxiliary film is formed over the semiconductor substrate including a surface of the first etch mask patterns. Second etch mask patterns are formed between the auxiliary films formed on sidewalls of the first etch mask patterns. The first etch mask patterns and the second etch mask patterns are formed using the same material. The auxiliary films between the first and second etch mask patterns are removed. Accordingly, more micro patterns can be formed than allowed by the resolution limit of an exposure apparatus while preventing misalignment.

  • Patent number: 7882380
    Abstract: A system and method for enabling or disabling clocks to one or more portions of hardware circuitry, for example a display sub-system of a personal computer. A processor generates a command or data to a first circuit configured to perform a function based at least on the command or data. A clock generator selectively supplies clocks to the first circuit and a second circuit configured to perform a second function. A software interface circuit coupled to the processor and the clock generator autonomously determines based at least on the command or data whether the second circuit will perform the second function or be idle in an upcoming period and disables one or more of the clocks to the second circuit if the second circuit will be idle in the upcoming period.

  • Patent number: 7877386
    Abstract: A user uses a graphical user interface to configure a search process. One or more set up pages may be output to the user to allow the search process to be configured. Once the search process is defined, a graphical user interface is generated that provides the search process. A searcher can then use the interface to perform searches. A search page is provided that includes fields that were defined. When a search term is received, a search is performed according to a search definition. The search results are then returned according to how the search results were configured. For example, the search results may be returned in a stepped fashion. Additionally, a quick create option is provided on the search result page. This allows a user to create an entry that is classified according to the search definition for the field that was searched.
