摘要： A translation is performed by using a programmable hashing technique on an input number to generate a hashed number. A subset of the hashed number bits are used to index a first hash table. In first hash table locations where a hash collision does not occur, the first hash table entry contains an index into an output table which contains the desired translated output number. In first hash table locations where a hash collision occurs, the first hash table entry contains a pointer to a first resolution table area in a second hash table. The first resolution table area contains entries which are indexed by additional bits selected from the hashed number in accordance with a mask field in the first hash table location. If collisions occur in the resolution table a new resolution table is created and the process is repeated. The resolution process thus proceeds in stages until all input numbers have been translated.
摘要翻译：通过在输入号码上使用可编程散列技术来执行翻译以产生散列数。散列数位的子集用于索引第一个散列表。在不发生哈希冲突的第一哈希表位置中，第一哈希表条目包含输出表中包含所需转换输出数的索引。在发生哈希冲突的第一哈希表位置中，第一散列表条目包含指向第二散列表中的第一分辨率表区域的指针。第一分辨率表区域包含根据第一散列表位置中的掩码字段从由散列数选择的附加位索引的条目。如果在分辨率表中发生冲突，则创建一个新的分辨率表，并重复该过程。因此，分辨率过程分阶段进行，直到所有输入数字已经被翻译。

摘要： Aspects of the invention include a method of conducting a reduced length search along a search path. A node which would otherwise occur between a previous and a following node in the search path is eliminated, and information is stored as to whether, had said eliminated node been present, the search would have proceeded to the following node. During the search, a search argument is compared with the stored information, and the search effectively progresses from the previous node directly to the following node if the comparison is positive. In preferred embodiments, some nodes provide result values for the search, and a node is eliminated only if its presence would not affect the result value for the search. In another aspect, the invention features a method of conducting a two mode search of reduced length. For a first mode of the search, nodes along a search path are provided, at least some of the nodes including one or more pointers pointing to other nodes. A search argument comprising a series of search segments is provided, some values of segments of the argument corresponding to nodes along the search path, some other values of the segments relating to a second mode of the search. Indicators associated with nodes are provided, each indicator indicating the segments corresponding to the second mode. The search path is searched by processing successive search segments by inspecting the indicator associated with each node, and proceeding to the second search mode if the indicator indicates that the segment relates to the second mode.
摘要翻译：本发明的方面包括沿搜索路径进行缩短长度搜索的方法。否则将发生在搜索路径中的先前节点和后续节点之间的节点，并且存储关于是否存在所述已消除的节点的搜索将进行到下一个节点的信息。在搜索期间，将搜索参数与存储的信息进行比较，如果比较为正，则搜索从前一节点直接进行到后续节点。在优选实施例中，一些节点为搜索提供结果值，并且仅当其存在不会影响搜索的结果值时才消除节点。另一方面，本发明的特征在于进行缩减长度的两种模式搜索的方法。对于搜索的第一模式，提供沿着搜索路径的节点，至少一些节点包括指向其他节点的一个或多个指针。提供了包括一系列搜索段的搜索参数，参数对应于沿着搜索路径的节点的段的一些值，与搜索的第二模式相关的段的一些其它值。提供与节点相关联的指示符，每个指示符指示对应于第二模式的段。通过检查与每个节点相关联的指示符来处理连续的搜索段来搜索搜索路径，并且如果指示符指示该段涉及第二模式，则进入第二搜索模式。

摘要： A backplane wiring scheme is provided for use in a hub of a packet data communications system. Line cards are connected to the backplane wiring arrangement in the hub, where each line card is a coupling to a network segment, a station or a to a bridge to other stations or segments. The connection is usually in either a ring or a bus topology, and increased flexibility, reduced power consumption, and easier implementation are provided by a unique wiring scheme. Each line card has a number of receive ports (e.g., N-1) and has two transmit ports, the transmit ports including a transmit-left port and a transmit-right port. The receive ports and transmit ports are arranged in a regular linear pattern on an edge of each of said line cards. The line cards are inserted in backplane slots, and backplane wiring paths are configured diagonally between ports of the cards to connect the transmit-left ports of the line cards to receive ports of line cards to the left and to connect the transmit-right ports of the line cards to receive ports of line cards to the right. When the transmit-left port and the transmit-right port of each of the line cards are connected together, the line cards are thereby configured as a bus. When only the transmit-left port and a top one of the receive ports are activated for all of the line cards, and the transmit-right port of only the left-most line card, are activated, the line cards are thereby configured as a ring.

摘要： An apparatus and method for receiving time skewed data from a parallel data bus. A data transfer on the parallel data bus is preceded by a start-of-cell delimiter consisting of a predetermined sequence of pulses on each of the data signals. The data is received from the bus by receive logic employing a local clock. Sampling logic is used to sample each of the data signals received from the bus at a rate which is higher than the local clock rate. Sample registers store a plurality of samples of corresponding data signals, the number of samples stored being large enough to store at least some of the pulses constituting the start-of-cell delimiter. Start-of-cell detect and center select logic is used for determining that a start-of-cell delimiter is stored in each of the sample registers, and for determining which of the samples stored in each of the sample registers represents the approximate center sample of one of the pulses of the start-of-cell delimiter. These center samples correspond to the data signals on the bus, but are de-skewed and synchronous with the local clock.

摘要： A bi-directional full duplex clocked bus including eight data lines, a clock line and a control line. The bus signals are low level differential with suitable drivers and receivers. The bus operation includes a protocol of sending groupings of eight bytes transmissions where a byte is sent on the rising and the falling edges of the clock signal. When reading the received data, delayed clocks are used that are formed at the center of both of the received clock signal phases. The delayed clocks may be used to output data on the outputs lines. The delayed clocks are arranged to be symmetrical with substantially no skew and centered to the phases of the received clock signal.
