Abstract: A method of communicating between nodes in a network where a node receives a sequence of symbols that will form a packet on a first communications channel and has a planned packet that it would send on a second communications channel. A destination is encoded into an arbitration portion of a header sequence of the packet, the header sequence comprising a sequence of symbols. The transmission on the second communications channel is as per the planned packet, for as long as the symbols of the planned packet match the symbols being received on the first channel. An arbitration decision is made when the symbols do not match, with the node either continuing to send the rest of the planned packet, or the rest of the packet being received on the first communications channel.

Abstract: A memory transparent in-system built-in self-test may include performing in-system testing on subsets of memory cells over one or more test intervals of one or more test sessions. A test interval may include copying contents of a subset of memory cells to a register(s), writing test data (e.g., a segment of a pattern) to the subset of memory cells, reading back contents of the subset of memory cells, and restoring the content from the register(s) to the subset of memory cells. In-system testing may be performed on overlapping sets of memory cells. In-system testing may be performed on successive subsets of memory cells within a row (i.e., fast column addressing) and/or within a column (fast column addressing). In-system testing may be performed on sets of m blocks of memory cells during respective test intervals. The number of m blocks tested per interval may be configurable/selectable.

Abstract: Message faulting is a critical unsolved problem for 5G and 6G. Disclosed herein is a method for combining an AI-based analysis of the waveform data of each message element, plus the constraint of an associated error-detection code (such as a CRC or parity construct of the correct message) to localize and, in many cases, correct a limited number of faults per message, without a retransmission. For example, the waveform data may include a deviation of the amplitude or phase of a particular message element, relative to an average of the amplitudes or phases of the other message elements that have the same demodulation value. The outliers are thereby exposed as the most likely faulted message elements. In addition, using the error-detection code, the AI model can determine the most likely corrected message, thereby avoiding retransmission delays and power usage and other costs.

A communication device encodes an input bit sequence by using an LDPC matrix, to obtain an encoded bit sequence for transmission.

Abstract: A system performs verification of Ethernet hardware. A data frame including a first portion for storing a checksum value and a second portion for storing a timestamp value is received. The second portion of data frame is set to zero. A timestamp value for including in second portion of the data frame is received. A modified checksum value is determined based on the checksum value included in the first portion of the data frame and the timestamp value. A cyclic redundancy check (CRC) value is determined for the data frame by nullifying the checksum value in the data frame and considering the timestamp value. A final CRC value is determined by combining the CRC value for the data frame and a CRC correction value based on the checksum. The modified data frame is sent for processing using an emulator.
