    摘要: A surround-vision display system with a very high visual dynamic range is made possible by distributing a limited number of LED's on the inside of a drum and then spinning that drum around a user. The pixel information for each horizontal position in space is sent to each corresponding LED it visits that position. The LED's are arranged in a grid on a panel tile, and the panel tile is tilted slightly, e.g., at 1.1-degrees. The result is each panel tile presents a continuous vertical stripe in the picture frame as all its LED's are swept by in the drum motion. Several panel tiles stacked vertically inside the drum all contribute to the whole height of the picture frame, e.g., several feet. The entire inside circumference of the drum is populated with the LED panel tiles to keep frame refresh rates up to avoid flicker while keeping drum rotation speeds down to reasonable levels. Thus even though the LED's and drum are moving, the image projected appears to be relatively stationary.

    摘要: A computer system has a plurality of processor nodes and a plurality of input/output nodes. Each processor node includes a multiplicity of processor cores, an interface to a local memory system and a protocol engine implementing a predefined cache coherence protocol. Each processor core has an associated memory cache for caching memory lines of information. Each input/output node includes no processor cores, an input/output interface for interfacing to an input/output bus or input/output device, a memory cache for caching memory lines of information and an interface to a local memory subsystem. The local memory subsystem of each processor node and input/output node stores a multiplicity of memory lines of information. The protocol engine of each processor node and input/output node implements the same predefined cache coherence protocol.

    摘要: L1 cache synonyms in a two-level cache system are detected and resolved by logic in the L2 cache. Duplicate copies of the L1 cache tags and state (“Dtags”) are maintained in the L2 cache. After a miss occurs in the L1 cache, the Dtags in the second-level cache that correspond to all possible synonym locations in the L1 cache are searched for synonyms. If a synonym is found, the L2 cache notifies the L1 cache where the requested cache line can be found in the L1 cache. The L1 cache then copies the cache line from the location where the synonym was found to the location where the miss occurred, and it invalidates the cache line at the original location. The Dtags in the second-level cache are updated to reflect the changes made in the L1 cache.

    摘要: Each node of a multiprocessor computer system includes a main memory, a cache memory system and logic. The main memory stores memory lines of data. A directory entry for each memory line indicates whether a copy of the corresponding memory line is stored in the cache memory system in another node. The cache memory system stores copies of memory lines and cache state information indicating whether the cached copy of each memory line is an exclusive copy. The logic of each respective node is configured to respond to a transaction request for a particular memory line and its corresponding directory entry, where the respective node is the home node of the particular memory. When the cache memory system of the home node stores an exclusive copy of the particular memory line, the logic responds to the request by sending the copy of the particular memory line retrieved from the cache memory system and a predefined null directory entry value, and thus does not retrieve the memory line and its directory entry from the main memory of the home node.

    摘要: A chip-multiprocessing system with scalable architecture, including on a single chip: a plurality of processor cores; a two-level cache hierarchy; an intra-chip switch; one or more memory controllers; a cache coherence protocol; one or more coherence protocol engines; and an interconnect subsystem. The two-level cache hierarchy includes first level and second level caches. In particular, the first level caches include a pair of instruction and data caches for, and private to, each processor core. The second level cache has a relaxed inclusion property, the second-level cache being logically shared by the plurality of processor cores. Each of the plurality of processor cores is capable of executing an instruction set of the ALPHA™ processing core. The scalable architecture of the chip-multiprocessing system is targeted at parallel commercial workloads. A showcase example of the chip-multiprocessing system, called the PIRANHA™ system, is a highly integrated processing node with eight simpler ALPHA™ processor cores. A method for scalable chip-multiprocessing is also provided.

    摘要: A system and method for operating a light emitting device utilizing charged quantum dots is described. In one embodiment, charged quantum dots are suspended in a liquid between an excitation plate and a cover plate. The excitation plate carries short-wave excitation light. Charged quantum dots near the surface of the excitation plate may emit light in response to an evanescent field generated by the short-wave excitation light undergoing total internal reflection within the excitation plate. The excitation plate and the cover plate may be coated with one or more transparent electrodes. The movement of charged quantum dots within the liquid may be controlled by applying one or more bias voltages to the one or more transparent electrodes. Light emission from a particular region near the surface of the excitation plate may be controlled by moving charged quantum dots into or out of the particular region.

    摘要: A stylus device receives light from a display though an optical element that is adapted to increase the field curvature of an image formed on an image sensor of the stylus device. Based on the size and shape of a portion of the image that is in focus, a distance, orientation, and/or azimuth of the stylus device with respect to the display can be determined. In addition, a position corresponding to each pixel, or groups of pixels, is encoded into blue light emitted by each pixel or group of pixels of the display. Upon initialization, or after a loss of synchronization, the stylus device can determine its position with respect to the pixels by decoding the encoded position. After synchronizing its position with the display, the stylus device can determine its subsequent positions by tracking pixels of the display.

    摘要: A stylus system and method for determining the three-dimensional position and orientation of a stylus operating within a volume located above a surface of a display device is described. In some embodiments, the stylus system includes a stylus and a display device. The stylus senses one or more magnetic fields generated from a set of transmitting coils associated with the display device and transmits sensing information over an RF channel to a receiver in the display device. The display device determines the three-dimensional position of the stylus by applying a cell-based position reconstruction technique that compares the received sensing information with predetermined magnetic field values associated with one or more predetermined regions located above the surface of the display device. The cell-based position reconstruction technique accommodates magnetic field distortions due to the presence of conductive elements within or near the display device.
