Abstract: In one embodiment, an apparatus cascades groups of serialized data streams through devices, and performs operations based on information communicated therein. A received group of serialized data streams is aligned, but not framed, and forwarded to a next device (e.g., a next stage in a linear or tree cascaded formation of devices). Eliminating the framing and subsequent serialization operations performed on the received group of serialized data streams reduces the latency of communications through the cascaded devices, which can be significant when considered in relation to the high-speed communication rates. The received group of serialized data streams is also framed to create a sequence of data frames for processing (e.g., associative memory lookup operations, controlling multiplexing of received downstream serialized data streams, general or other processing) within the device.

Abstract translation: 在一个实施例中，设备通过设备级联串联数据流组，并且基于在其中传达的信息执行操作。 所接收的一组串行化数据流被对齐，但不被成帧，并被转发到下一个设备（例如，设备的线性或树形级联形成中的下一级）。 消除对所接收的串行化数据流组执行的成帧和随后的串行化操作减少了通过级联设备的通信的延迟，当考虑高速通信速率时，这可能是重要的。 接收到的串行数据流组也被成帧以创建用于处理（例如，关联存储器查找操作，控制所接收的下游串行化数据流的多路复用，通用或其它处理）的数据帧序列。

Abstract: An apparatus has at least one processing unit to generate a request having a request privilege level. At least one resource exists in the apparatus to receive the request and determine if the request is allowable. The apparatus includes an error handler that determines the nature of an error and performs a reset based upon the privilege level of the request that cause the error.

Abstract: Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms, and means for communicating with a memory device, such as by a memory controller, a refresh command at least partially overlapping in time with a read and/or write command. The refresh command typically specifies a group of locations (e.g., a bank) for being at least partially refreshed.

Abstract: The invention provides a method of encoding a data packet for encapsulation in one or more frames for communication from a transmitter to a receiver in a network interface. The method includes dividing the data packet into one or more data chunks and determining the length of a data chunk as the lesser of the number of bytes available in a current frame, the number of bytes remaining in the data packet, or a predetermined number of bytes. The method includes determining if the data chunk is the end-of-the-packet (EOP) and when the data chunk is not the EOP, the method includes prepending the data chunk with a control character representing the length of the data chunk and non-EOP.

Abstract translation: 本发明提供了一种编码用于在一个或多个帧中进行封装的数据分组的方法，用于在网络接口中从发射机到接收机进行通信。 该方法包括将数据分组划分为一个或多个数据块，并将数据块的长度确定为当前帧中可用的字节数的少一个，数据分组中剩余的字节数或预定数量的 字节。 该方法包括确定数据块是否是分组结束（EOP），并且当数据块不是EOP时，该方法包括使用表示数据块的长度的控制字符预先添加数据块，而非 -EOP。
