Speculative cache tag evaluation
A cache tag comparison unit in a cache controller evaluates tag data and error correction codes to determine if there is a cache hit or miss. The cache tag comparison unit speculatively compares the tag data with the request tag without regard to error correction. The error correction code verifies whether this initial comparison is correct and provides a confirmed cache hit or miss signal. The tag data is compared with the request tag to determine a provisional cache hit or miss, and in parallel, the error correction code is evaluated. If the error code evaluation indicates errors in the tag data, a provisional cache hit is converted into a cache miss if errors are responsible for a false match. If the error code evaluation identifies the locations of errors, a provisional cache miss is converted into a cache hit if the errors are responsible for the mismatch. |

Firmware routines executed by a control and dispatch unit that is normally part of any memory controller hub enable it to implement any of six different checkpointing strategies: post-image checkpointing in which an image of the system state at the time of the last checkpoint is maintained in a local shadow memory; post-image checkpointing in which an image of the system state at the time of the last checkpoint is maintained in a shadow memory located in a second, backup computer; post-image checkpointing using a bit-map memory, having one bit representing each data block in system memory, to reduce the amount of memory-to-memory copying required to establish a checkpoint; post-image checkpointing to a local shadow memory using two bit map memories to enable normal processing to continue while the shadow is being updated, post-image checkpointing to a local shadow memory using a block-state memory that eliminates the need for any memory-to-memory copying; and local pre-image checkpointing that does not require a shadow memory. Since each of these implementations has advantages and disadvantages relative to the others and since similar mechanisms are used in the memory controller hub for all of these options, it can be designed to support all of them with hardwired or settable status bits defining which is to be supported in a given situation. |

Accelerated data switching on symmetric multiprocessor systems using port affinity
A router that includes a plurality of processors (SMPs) where there is “affinity” between particular processors and particular interfaces: Each of the router's interfaces are assigned to one of the processors. A packet arriving at a particular interface will be handled by the processor having an affinity to that particular interface. If the packet's egress is on an interface assigned to the same processor, then the output process will also be handled by that processor. If the egress interface has an affinity to a different processor, then the packet is handed over to the other processor for egress. The data structures that must be retrieved from memory to handle a packet are often associated with the interfaces through which the packet passes. Thus, having a particular processor handle all the packets that pass through a particular interface insures that the data structures needed to handle the packets will more likely be stored in the processor's cache and less likely be the object of inter-processor lock contention. |

Using sibling-count in XML indexes to optimize single-path queries
A method and apparatus are provided for using sibling-counts in XML indices to optimize single-path queries. Using a b-tree XML index with a SQL query logarithmically reduces the number of disk accesses by passing over index entries where it is determined that a match will not be found. However, because certain index entries are passed over, it is impossible to ascertain if a path expression occurs more than once in the XML index, as certain queries sometimes require. This hurdle can be overcome by maintaining a sibling count with each node entry in the XML index. Because the sibling count is stored with the index entry, the index will reveal whether the matching node is single or has other siblings. In additional to re-writing the original query for optimization by use of an XML index, it will be re-written to check for a single-path condition in the index. |

Broadcast receiving terminal
Although a scheduled recording that is set by an EPG (Electronic Program Guide) specifies in advance a time slot for using the resource, reproduction that is set by the EPG does not specify a time slot for using the resource. Therefore, although it is possible to carry out resource allocations for a plurality of scheduled recordings in advance, it is not possible to carry out a resource adjustment in advance when the scheduled recording and the reproduction operation use the same resource. However, when an adjustment process is performed after the starting time of the scheduled recording, the adjustment process itself takes up some time, thus giving rise to the possibility that the scheduled recording may not start at the specified starting time. The resource adjustment for the scheduled recording and the reproduction is initiated ahead of the starting time of the scheduled recording. The amount of time ahead of the scheduled recording, by which the resource adjustment is to be started, can be specified by the EPG. |

Street-side maps and paths
The claimed subject matter relates to a computer-implemented architecture that can generate a map. The map can be a hybrid between an orthographic projection map and street-side images, thus including useful aspects from both types of representations. For example, an orthographic projection map is very effective at presenting global relationships among the features of the map, but not effective at presenting local detail. In contrast, street-side images show excellent detail, but do not convey the global information of an orthographic projection map. The hybrid map can thus provide a richer set of information than conventional maps, and can also display objects/features of the hybrid map in multiple perspectives simultaneously on a single representation that is printable. |

Method for the organization of network nodes in a packet-switched network
There is described a method to organize a network, wherein if for a first router set up as the default gateway an inaccessibility of an assigned network element is detected at an interface of the first router a second router is set up as the logical default gateway. In this case a provision is made such that in the course of setting up the second router as the default gateway a check on the interface metric is performed at the first and/or second router and that in consequence of the inaccessibility detected for the interface an adaptation of the interface metric is carried out. The interface metric is propagated for example by way of the routing protocol OSPF and/or EIGRP and/or IS-IS to other routers. When using the method it is possible in a failure scenario with divided Layer-2 networks to avoid an occurrence of “black holes”, in other words gaps in communication. Moreover asymmetric routing, which is caused by a changeover of the logical gateway from the first router to the second router, can be eliminated. The danger of an excessive exchange of unicast messages, which can result in a high failure level of all participating network nodes and network node elements, is thus also excluded. |

Systems and methods of direct volume rendering
A method and system of increasing the speed of a ray-casting algorithm for producing direct volume rendering images in the melt-through interaction mode. Since the viewing direction is not changed during a melt-through interaction, it is possible to reuse the samples calculated along each ray from one frame to another. The samples along each ray are partitioned into different groups, and the samples within each partition can be composited to generate an RGBA-tuple (Red Green Blue and Alpha, which is an opacity factor) for the partition. The associative property of the composition operation allows computation of the final RGBA value for each ray by compositing the RGBA-values of the partitions, instead of compositing the RGBA-values of each sample along the ray. |

Virtual endoscopy
In a virtual endoscopy method, an unfolding axis (100, 100′) substantially along an elongated lumen (150) is divided into axis segments (110). Ray casting directions (104) are selected extending generally radially from the axis segments. At least some of the ray casting directions are tilted away from a camera position (102). Ray casting is performed along the tilted ray casting directions to define pixel values that are arranged into an unfolded view. The ray casting employs at least one of (i) volume rendering and (ii) computing a statistical characteristic of voxels (238) over a preselected distance (dinterval) along the ray casting direction into the lumen-defining structure. |

Display driver and display panel module
A display driver includes: a first memory circuit for storing a line of pixels constituting an image; a second memory circuit for storing pixels of the immediately previous line; an output terminal pair switch circuit which outputs voltages each corresponding to a value of a pixel stored in the first memory circuit to a plurality of output terminals respectively corresponding to the pixels; and an inter-terminal load determination circuit for determining, for every pair of selected columns of pixels constituting the image, whether or not a short circuit is to be established between two of the plurality of output terminals which respectively correspond to the two selected columns based on values of at least three out of four pixels belonging to the two selected columns which are stored in the first and second memory circuits. If the inter-terminal load determination circuit determines that a short circuit is to be established, the output terminal pair switch circuit temporarily establishes a short circuit between the two output terminals before the voltages corresponding to the values of the pixels are output to the two output terminals. |
