    • In general, in one aspect, the disclosure describes a multiplier that includes a set of multiple multipliers configured in parallel where the set of multiple multipliers have access to a first operand and a second operand to multiply, the first operand having multiple segments and the second operand having multiple segments. The multiplier also includes logic to repeatedly supply a single segment of the second operand to each multiplier of the set of multiple multipliers and to supply multiple respective segments of the first operand to the respective ones of the set of multiple multipliers until each segment of the second operand has been supplied with each segment of the first operand. The logic shifts the output of different ones of the set of multiple multipliers based, at least in part, on the position of the respective segments within the first operand. The multiplier also includes an accumulator coupled to the logic.
    • 通常,在一个方面,本公开描述了一种乘法器,该乘法器包括并行配置的一组多个乘法器,其中多个乘法器的集合可以访问第一操作数和第二操作数以便相乘,第一操作数具有多个段并且第二操作数 操作数有多个段。 乘法器还包括逻辑,用于重复提供第二操作数的单个段到该组多个乘法器中的每个乘法器,并且将第一操作数的多个相应段提供给该多个乘法器集中的相应乘法直到第二个 操作数已经与第一个操作数的每个段一起提供。 该逻辑至少部分地基于第一操作数内的各个段的位置来移位该多个乘法器组中的不同者的输出。 乘法器还包括一个连接到逻辑的累加器。

    • An embodiment may include circuitry to determine, at least in part, whether one or more reference patterns are present in a data stream in a packet flow. The circuitry may include first pattern matching circuitry communicatively coupled to second pattern matching circuitry. The first pattern matching circuitry may determine, based at least in part upon one or more deterministic pattern matching operations, whether at least one portion of the one or more reference patterns is present in the stream. If the first pattern matching circuitry determines that the at least one portion of the one or more reference patterns is present in the stream, the second pattern matching circuitry may determine, based at least in part upon one or more pattern matching threads, whether at least one other portion of the one or more reference patterns is present in the stream. Many modifications are possible without departing from this embodiment.
    • 一个实施例可以包括用于至少部分地确定一个或多个参考模式是否存在于分组流中的数据流中的电路。 该电路可以包括通信地耦合到第二模式匹配电路的第一模式匹配电路。 第一模式匹配电路可至少部分地基于一个或多个确定性模式匹配操作来确定一个或多个参考模式的至少一部分是否存在于流中。 如果第一模式匹配电路确定一个或多个参考模式的至少一部分存在于流中,则第二模式匹配电路可以至少部分地基于一个或多个模式匹配线确定是否至少 一个或多个参考图案的另一部分存在于流中。 在不脱离本实施例的情况下可以进行许多修改。
