摘要: The invention pertains to communication among stations interconnected by a ring of physical links, operating at a base symbol rate. Each station has an upstream and a downstream link and relays messages originating from the upstream link to its downstream link. Logical links are provided on the ring, each associated with a symbol rate divisor and a link index. Each station transmits messages composed of a strings of symbols on a selected logical link by transmitting the message on its downstream link at the base symbol rate divided by the symbol rate divisor associated with the selected logical link, and offset by the link index of the selected logical link. A station generates a first synchronizing sequence on its downstream link at the base symbol rate divided by the symbol rate divisor associated with a first logical link not used for data, and offset by the link index of the first logical link, and a second synchronizing sequence at the base symbol rate divided by the symbol rate divisor associated with a second logical link not used for data, and offset by the link index of the second logical link.

摘要: Systems or methods of the present disclosure may improve scalability (e.g., component scalability, product variation scalability) of integrated circuit systems by disaggregating periphery intellectual property (IP) circuitry into modular periphery IP tiles that can be installed as modules. Such an integrated circuit system may include a first die that includes programmable fabric circuitry and a second die that that includes a periphery IP tile. The periphery IP tile may be disaggregated from the programmable fabric die and may be communicatively coupled to the first die via a modular interface.

摘要: Methods, devices, and systems are provided to determine traffic conditions along a traffic path and dynamically present one or more entities with at least one alternate route. The alternate route is determined based on a number of entities along the traffic path and available routing points adjacent to the traffic conditions. The alternate route may be configured to optimize traffic for an entire traffic system rather than only optimizing traffic for receivers of the alternate routes. Data relating to the alternate routes presented to the entities can be tracked. This data may be used to evaluate an effectiveness of the routing decisions made. Effectiveness can be measured in cost and time saved or spent. Information, such as the data, determinations of the data, and/or even effectiveness of alternate routes, can be distributed to one or more parties. Distribution of the information may be associated with a tiered cost structure.

摘要: A communication device that performs bidirectional multiplex communication between a plurality of slave communication devices and the communication device is provided with: a first port connected to one end section of a transmission line to which the slave communication devices are connected; a second port connected to the other end section of the transmission line; and a current detection unit connected to the first port and the second port. An operation voltage is supplied from the communication device to the slave communication devices, a change of the quantity of a current flowing in the first port and/or the second port is detected by means of the current detection unit, and on the basis of the current quantity change, occurrence of disconnection in the transmission line is detected.

摘要: Aspects of traffic aware slot assignment are described, for example, in a multi-hop wireless network comprising a plurality of nodes. In some aspects, an apparatus of a wireless device is configured to decode signaling, received from a node of the multi-hop network, to determine an indication of a change to a topology of the multi-hop network. The apparatus is further configured to, in response to a determination, from the decoded signaling, of an addition of a second node to the multi-hop network topology, increment a total of a number of descendant nodes, and allocate one or more transmission slots to a number of unused slots in one or more transmission opportunity regions of a slotframe, wherein the slotframe includes a repeating pattern of one or more transmission opportunity periods for a plurality of nodes in the network.

摘要: Technologies for scalable packet reception and transmission include a network device. The network device is to establish a ring that is defined as a circular buffer and includes a plurality of slots to store entries representative of packets. The network device is also to generate and assign receive descriptors to the slots in the ring. Each receive descriptor includes a pointer to a corresponding memory buffer to store packet data. The network device is further to determine whether the NIC has received one or more packets and copy, with direct memory access (DMA) and in response to a determination that the NIC has received one or more packets, packet data of the received one or more packets from the NIC to the memory buffers associated with the receive descriptors assigned to the slots in the ring.

摘要: Transmitted signals are modified to facilitate the emulation of circular convolution in non-contiguous transmission environments. These modified signals may be derived from well-known signature sequences. In an exemplary method, a tail portion of a final segment of a base signal is prefixed to an initial segment of the base signal, to form a first transmit segment. One or more additional transmit segments are formed by prefixing, to each of the one or more segments of the base signal other than the initial segment, a tail portion of the immediately preceding segment of the base signal. The transmit segments so formed are transmitted in respective ones of the plurality of non-contiguous transmit-time intervals. Corresponding methods for receiving the transmitted segments and reconstructing the base signal are also described, as are corresponding transmitting and receiving apparatuses.
