摘要： A network switch includes a look-up engine for obtaining associated data in response to a header portion of a packet and an interlinked network processor such as a RISC for performing a processing function on the header portion or the associated data. Both look-up engine and the network processor may modify a destination port bitmask. The network processor may implement additional packet header processing required for replication or server load balancing.

摘要： A communication device which includes a hardware trie search facility. At least part of a memory is divided into memory blocks, each of said blocks consisting of a multiplicity of locations, at least some of said locations each providing when accessed a pointer to another block and an indication of the size of the block. A shift register holds an address key, and a trie block is accessed using an address composed of a number of bits related to said indication of the size of the block. The key is shifted by said number of bits prior to a subsequent stage of the search. Part of the memory comprises an associated data table which includes entries of data enabling a packet to be forwarded and at least some locations in said blocks provide when accessed a pointer to an entry in the associated data table.

摘要： A method and system for performing retail transactions allows use of a wireless device in lieu of conventional financial cards. A retail system sends customer-independent transaction data, which is matched with a customer account associated with a wireless device. A customer sends a wireless communication from a wireless device to a server. The server identifies the wireless device and identifies a customer account associated with the wireless device. The customer account and the customer-independent transaction data are matched together, authorizing the retail transaction. When multiple retail transactions occur within a short time, a matching technique scores matches between multiple retail transactions and multiple customer-initiated wireless communications.

摘要： A program tool automatically generating interconnect logic for a system-on-a-chip is based on a library of operational cores and on a architecture which requires all data exchange between cores to proceed via shared memory, which may be ‘off-chip’. The architecture includes a data aggregation technique for access to memory with successive levels of arbitration.

摘要： A pipelined image processor is disclosed which contains a diagnostic apparatus which, under normal processing conditions, is coupled to and is in communication with resequencer, image processor, and transposer/compressor assemblies contained within the pipelined image processor. The diagnostic apparatus of this invention causes a diagnostic test pattern to be sent to the re-sequencer and image processor entities of the pipelined image processor and monitors the response thereof. This response is then used to detect faults which have occurred in these entities.

摘要： The present invention is based on a ring architecture wherein each chip in the multiplicity of chips is connected in a chain so that it can receive packets from the next previous chip in the chain and forward packets to the next following chip in the chain, whereby to form a ring. Before a packet is placed on the ring by a device it is provided with a ‘masking’ field which identifies each of the other devices and the ports within any such device to which the packet must be sent in order to achieve a multicast. When a device in its turn receives such a packet it will examine the masking field to determine whether the field identifies that device. If so, the packet, which may be held in temporary storage, may be processed for forwarding from a port of that device. The device will strip from the masking field the identification of the respective device and transmit the packet with a thus modified masking field to the next device in turn. If a packet does not contain any indication of another device in the ring, the packet will not be transmitted and therefore will naturally terminate.
摘要翻译：本发明基于环形结构，其中多个芯片中的每个芯片以链路连接，使得其可以从链中的下一个先前芯片接收分组，并将分组转发到链中的下一个后续芯片，由此到形成戒指在通过设备将数据包放置在环上之前，它被提供有“掩蔽”字段，其标识每个其他设备以及要向其发送分组的任何这样的设备中的端口以实现多播。当设备反过来接收到这样的分组时，它将检查掩蔽字段以确定该字段是否标识该设备。如果是这样，则可以处理可以保存在临时存储器中的分组，以从该设备的端口转发。设备将从掩蔽字段剥离相应设备的标识，并将具有如此修改的掩蔽字段的分组依次传送到下一个设备。如果一个分组不包含环中另一个设备的任何指示，则该分组将不被传输，因此将自然地终止。

摘要： A system including an ordered data table containing linked lists of MAC addresses has a multiplicity of search engines which have their access to an LRU engine under the control of a token which is passed from one search engine to the next when the LRU engine has completed reordering the table after an address look-up. The system avoids conflicts between searching and reordering and allows reordering to be performed at a controlled rate.
摘要翻译：包括含有MAC地址的链接列表的有序数据表的系统具有多个搜索引擎，它们在LRU引擎已经完成重排序的情况下，在令牌的控制下访问LRU引擎，该令牌从一个搜索引擎传递到下一个搜索引擎表后地址查找。该系统避免了搜索和重新排序之间的冲突，并允许以受控的速率执行重新排序。
