摘要： A fast pseudo-random number generator, which can be employed in a variety of systems such as a stream cipher cryptosystem or a Monte Carlo simulation system, includes a linear feedback shift register (LFSR) having a state contained in N storage elements storing N bits of binary data which are separated into w words having word length M. At least two tap sources provide binary data, each tap source has a number of bits which is a multiple of M. The LFSR also includes a linear feedback function coupled to tap sources and providing a temporary value which is a linear function, such as bit-wise exclusive-or, of the binary data provided from the tap sources. The LFSR state is advanced by shifting the binary data in the storage elements by a multiple of M bits and provide the temporary value to fill in storage elements that would otherwise be empty from the shifting.

摘要： One embodiment comprises a network that includes a plurality of bi-directional links and a plurality of nodes. Each node is communicatively coupled to two neighbor nodes and to two skip nodes using the plurality of bi-directional links. Three neighboring nodes of the plurality of nodes form a triple modular redundant (TMR) set having a first end node, a second end node, and a center node, the first end node configured to transmit output data in a first direction and the second end node configured to transmit output data in a second direction. At least one of the plurality of nodes that is not in the redundant set determines the integrity of data received from the redundant set based on at least: (i) a comparison of data received on a first logical communication channel from a respective first neighbor node with data received on the first logical communication channel from a respective first skip node; (ii) a comparison of data received on a second logical communication channel from a respective second neighbor node with data received on the second logical communication channel from a respective second skip node; and (iii) a comparison of data received on the first logical communication channel from one of the respective first neighbor node and the respective first skip node with data received on the second logical communication channel from one of the respective second neighbor node and the respective second skip node.

摘要： A cluster comprises a plurality of end nodes that communicate with one another over at least one communication channel. Each end node is assigned a time slot for transmission of frames; wherein each node comprises a local guardian configured to prevent transmission of timing-related frames sourced from the respective end node. The cluster also comprises a special node that communicates with the plurality of end nodes, wherein the special node establishes a time base and sources timing-related frames to the plurality of end nodes. The transmission schedule includes at least one common scrubbing time slot during which each of the plurality of end nodes is configured to generate a timing-related frame. The special node is configured to determine if the local guardian in any of the plurality of nodes failed to prevent transmission of the respective generated timing-related frame during the common scrubbing time slot.

摘要： In one embodiment, a node comprises an interface to communicatively couple the node to a channel. The channel communicatively couples the node to a first neighbor node and first neighbor's neighbor node in a first direction. When the first neighbor node is scheduled to transmit and the node receives data from the first neighbor node via the channel, the node forwards the data to the first neighbor's neighbor, receives other data from the first neighbor's neighbor, compares the data to the other data, and relays the data along the channel with information indicative of the comparison.
