    Abstract: Methods, systems, and devices for redundant data bus inversion (DBI) sharing are described. A device may identify a group of channels included in a data bus. The device may determine whether the group of channels satisfies a criterion. Based on the determination, the device may allocate an overhead channel to the group of channels for a set of redundancy operations. Based on the determination, the device may allocate the overhead channel to the group of channels for a set of data bus inversion operations. The device may encode data associated with the group of channels based on the allocation of the overhead channel. The overhead channel may be included in the data bus.

    Abstract: A method in a communication network includes defining a root congestion condition for a network switch if the switch creates congestion in the network while switches downstream are congestion free, and a victim congestion condition if the switch creates the congestion as a result of one or more other congested switches downstream. A buffer fill level in a first switch, created by network traffic, is monitored. A binary notification is received from a second switch, which is connected to the first switch. A decision whether the first switch or the second switch is in a root or a victim congestion condition is made, based on both the buffer fill level and the binary notification. A network congestion control procedure is applied based on the decided congestion condition.

    Abstract translation: 通信网络中的一种方法包括：如果交换机在网络中产生拥塞，而下游的交换机拥塞不足则定义网络交换机的根拥塞状况;以及如果交换机由于一个或多个其他 下游拥塞交换机。 监视由网络流量创建的第一交换机中的缓冲区填充级别。 从连接到第一开关的第二开关接收二进制通知。 基于缓冲器填充级别和二进制通知，进行第一交换机或第二交换机是否处于根或者拥塞状态的判定。 基于确定的拥塞状况应用网络拥塞控制过程。

    Abstract: An apparatus includes operational circuitry and Hardware Diagnostics Circuitry (HDC). The HDC is configured to receive a definition of multiple trigger rules, each trigger rule specifying a respective trigger event as a function of trigger data sources in the operational circuitry, to receive a definition of (i) a pre-trigger logging set selected from among a plurality of diagnostics data sources in the operational circuitry, and (ii) for each trigger rule, a respective post-trigger logging set including a set of one or more of the diagnostics data sources, and, during operation of the operational circuitry, to log the diagnostics data sources in the pre-trigger logging set, to log the trigger data sources and to repeatedly evaluate the trigger rules, and, in response to triggering of a given trigger event by a given trigger rule, to start logging the diagnostics data sources in the post-trigger logging set of the given trigger rule.
