摘要： A method for routing data by a node from a plurality of nodes connected by links to form a network includes feeding, to a global bus, local traffic information regarding the node, the global bus being provided separately from the links and spread within the network. The method also includes obtaining, from the global bus, global traffic information regarding other nodes from the plurality of nodes. The method further includes switching a routing path of the data based on at least the local traffic information regarding the other nodes.

摘要： A method is provided for detour routing in a mesh network that includes nodes and bi-directional links connecting neighboring nodes. The method identifies any primary links useable to decrease a path distance from a source to a destination node. The method randomly selects one primary link for use, responsive to identifying more than one primary link that is non-defective. The method identifies any secondary links useable to decrease the path distance and orthogonal to a primary link, responsive to the primary links being defective. The method randomly selects one secondary link for use, responsive to identifying more than one secondary link that is non-defective. The method identifies any tertiary links useable to decrease the path distance and reverse in direction to a primary link, responsive to the secondary links being defective. The method sends a packet from the source to the destination node using the identified tertiary links.

摘要： A method is provided for packet broadcasting in a mesh-interconnected multi-computer network having a plurality of routers and a plurality of arbiters. The method includes interconnecting each of the plurality of routers to each of the plurality of arbiters. The method further includes receiving, by each of the plurality of arbiters, two or more packet broadcast requests. The method also includes live-lock free arbitering, by each of the plurality of arbiters, between the two or more packet broadcast requests using a shared priority matrix that selects one of the two or more packet broadcast requests. The shared priority matrix is shared amongst the plurality of arbiters and stores priority information relating to a correspondence between a plurality of packet broadcast requests, including the two or more packet broadcast requests, with respect to priorities assigned to each of the plurality of packet broadcast requests.

摘要： A method is provided of initializing a chip having synaptic NVRAM cells connected row-wise by word lines and column-wise by bit lines. The method includes driving, on selected word lines from among the word lines, a wave generated by a PLL circuit. The method includes generating standing waves from the wave on the selected lines by implementing a resonance detection point at an input end of each word line. The method includes applying a write voltage on all bit lines. The method includes simultaneously driving each of the synaptic NVRAM cells of the selected lines by different writing currents for different durations in order to set different analog values to the synaptic NVRAM cells.

摘要： A method, system, and data structure for sending data in a network which includes a plurality of nodes is provided. The method includes sending the data from a source node to an intermediate node. The method also includes sending the data from the intermediate node to plural destination nodes within a portion of the network. The portion is defined based on at least one physical distance from the intermediate node.

摘要： Provided are a power transmitting device, a power receiving device, a power supply system, and a power supply method able to supply electric power by emitting electromagnetic waves. A power transmitting device comprises: a calculating unit for calculating the maximum value for the emitted output of electromagnetic waves meeting exposure standards on the basis of a response delay time measured by the communication link between the power transmitting device and a power receiving device; a power transmitting unit for transmitting power via a power supply link with the power receiving device at an output not exceeding the maximum value; an anomaly detecting unit for detecting an anomaly in the power supply link on the basis of communication with the power receiving device via the communication link; and an output control unit for controlling the output on the basis of the detection of an anomaly in the power supply link.

摘要： A system and method of avoiding loss of memory trace data, including monitoring a first-in-first-out (FIFO) buffer to determine if the FIFO buffer has overflowed due to memory access, determining whether an overflow of the FIFO buffer is acceptable, changing an operating mode of a target system if overflow of the FIFO buffer is unacceptable to avoid FIFO buffer overflow, and collecting memory trace data on the memory accesses.

摘要： Described is a computer-implemented method for preventing time out during data transfer to an input/output device. Dummy data is generated and transferred to the input/output device at a time during data transfer, such as when a time out event may occur that would end the data transfer. The transfer of dummy data prevents a time out event from occurring.
