  • Patent number: 8085888
    Abstract: In various embodiments of the present invention, optimal or near-optimal multidirectional context sets for a particular data-and/or-signal analysis or processing task are determined by selecting a maximum context size, generating a set of leaf nodes corresponding to those maximally sized contexts that occur in the data or signal to be processed or analyzed, and then building up and concurrently pruning, level by level, a multidirectional optimal context tree constructing one of potentially many optimal or near-optimal context trees in which leaf nodes represent the context of a near-optimal or optimal context set that may contain contexts of different sizes and geometries. Pruning is carried out using a problem-domain-related weighting function applicable to nodes and subtrees within the context tree. In one described embodiment, a bi-directional context tree suitable for a signal denoising application is constructed using, as the weighting function, an estimated loss function.

  • Patent number: 8085289
    Abstract: An optical beam is selectively output towards a scanner in accordance with image data for a scan line of an image. The optical beam has a beam irradiance distribution that is elliptical in shape. The optical beam passes through an aperture stop, ordinarily creating side lobes within a focus irradiance distribution of the optical beam. The scanner scans the optical beam to form the scan line on a photosensitive surface by selectively exposing positions along the scan line in accordance with image data. The optical beam is modified before it reaches the photosensitive surface to substantially remove the side lobes that have been created within the focus irradiance distribution and/or to substantially prevent the side lobes from being created within the focus irradiance distribution of the optical beam.

  • Patent number: 8086555
    Abstract: A collaborative filtering method for evaluating a group of items to aid in predicting utility of items for a particular user comprises assigning an item value of either known or missing to each item of the group of items, and applying a modification scheme to the item values of the missing items to assign a confidence value to each of the item values of the missing items to thereby generate a group of modified item values. The group of items having modified item values and the group known items are evaluated to generate a prediction of utility of items for a particular user.

  • Patent number: 8086765
    Abstract: Illustrated is a system and method for identifying a memory page that is accessible via a common physical address, the common physical address simultaneously accessed by a hypervisor remapping the physical address to a machine address, and the physical address used as part of a DMA operation generated by an I/O device that is programmed by a VM. It also includes transmitting data associated with the memory page as part of a memory disaggregation regime, the memory disaggregation regime to include an allocation of an additional memory page, on a remote memory device, to which the data will be written. It further includes updating a P2M translation table associated with the hypervisor, and an IOMMU translation table associated with the I/O device, to reflect a mapping from the physical address to a machine address associated with the remote memory device and used to identify the additional memory page.

  • Patent number: 8085801
    Abstract: A circuit includes queue buffers, a bid masking circuit, and a priority selection circuit. Each of the queue buffers carries packets of a respective message class selected from a set of message classes and asserts a respective bid signal indicating that the queue buffer carries a packet that is available for transmission. The bid masking circuit produces a masked vector of bid signals by selectively masking one or more of the bid signals asserted by the queue buffers based on credit available to transmit the packets and on cyclical masking of one or more of the bid signals asserted by ones of the queue buffers selected for packet transmission. The priority selection circuit selects respective ones of the queue buffers from which packets are transmitted based on the masked vector of bid signals produced by the bid masking circuit.
