摘要： A method for reducing observed processing latency in networked communication, the method comprising: receiving a first portion of data, the data consisting of the first portion and a second portion; initializing data processing on the data after receiving the first portion of data and before receiving the second portion of the data; receiving the second portion of the data, the second portion of the data including error-detection code; performing error detection on the data based on the error-detection code; in response to the error detection indicating that the data is valid, finalizing data processing on the data and committing a data-processing result; and in response to the error detection indicating that the data is invalid, performing an error-correction process.

摘要： Packets are routed in a wireless mesh network by assigning a probability of packet retransmission based on certain factors which may include the number of hops the packet has made, whether the destination is within a certain number of known hops of the receiving node, the number of nearby nodes, whether the receiving node is a member of a past known route to the destination and/or whether a nearby neighbor of the receiving node is a member of a past known route to the destination. Once a probability is assigned, a random number generator may be used to make a decision between retransmitting the packet and dropping the packet. Signal quality may also be used as a factor in the probability of retransmission. In a preferred embodiment, Bloom filters are used to store information in the header of a data packet containing the identifiers of forwarding nodes and the identifiers of nodes on a previously-successful route from the source to the destination.

摘要： A system for writing to a cache line, the system including: at least one processor; and at least one memory having stored thereon instructions that, when executed by the at least one processor, controls the at least one processor to: pre-emptively invalidate a cache line at a reader device; receive, from the reader device, a read request for the invalidated cache line; delay a response to the read request; and after the delay, output for transmission a response to the read request to the reader device.

摘要： A system including: a reader; a writer; and a shared memory shared by the reader and the writer, wherein the writer is configured to: specify, in the shared memory, first and second cache lines as unsafe to read; prefetch sole ownership of the first and second cache lines; specify, after the prefetching, that the first and second prefetched cache lines are safe to read; write data to the first prefetched cache line in the shared memory; and in response to completing writing data to the first prefetched cache, relinquish control of the first prefetched cache line to a reader.
