摘要： A bandwidth divider and method for allocating bandwidth between a plurality of packet processors. The bandwidth divider includes a plurality of counters for measuring the bandwidth of data packets transferred from the bandwidth divider to a respective packet processor; and a controller for analyzing the plurality of counters and transferring a data packet to a selected packet processor based on the contents of the counters. The method monitors the bandwidth consumed by the packet processors; determines, based on the bandwidth consumed by the packet processors, which packet processor has consumed the least amount of bandwidth; and allocates a next data packet to the packet processor which has consumed the least amount of bandwidth.

摘要： In one embodiment, an apparatus includes a switch core that has a multi-stage switch fabric. The multi-stage switch fabric has a set of ingress ports and a set of egress ports. The switch core can be configured to be coupled to a set of edge devices via the set of ingress ports and the set of egress ports. The switch core can be configured to receive a packet from an ingress port from the set of ingress ports. The switch core can be configured to send a set of cells associated with the packet from the ingress port to an egress port from the set of egress ports without a store-and-forward delay associated with a zero-load latency for the switch core.

摘要： A hierarchical round robin arbiter includes a first set of arbitration vectors, each associated with a plurality of requesters. A second arbitration vector includes one bit for each arbitration vector in the first set. The single bit informs the round robin arbiter if any of the requesters associated with the corresponding arbitration vector in the first set are requesting service. The round robin arbiter can determine whether one of a number of requesters is requesting service by examining the single bit in the arbitration vector.

摘要： A method of prefiltering is applied before data compression of scanned image data to better preserve important information. Before prefiltering, the image is segmented and tagged as belonging in a first region, such as a Lineart region, in which edges are the most important information, or a second region, such as a Contone or Halftone Region, in which pixel level is the most important information. For prefiltering, dynamic filters condition the image data passing into the two compressors. Each filter attempts to suppress noise associated with its particular channel by applying a smoothing filter, no filter or a sharpening filter based on segmentation tags and other characteristics of the data.
摘要翻译：在扫描图像数据的数据压缩之前应用预过滤的方法以更好地保存重要信息。在预过滤之前，图像被分割并标记为属于第一区域，例如其中边缘是最重要信息的Lineart区域，或第二区域，例如Contone或半色调区域，其中像素级别为最重要的信息。对于预过滤器，动态过滤器将图像数据转化为两个压缩机。每个滤波器尝试通过基于分段标签和数据的其他特征应用平滑滤波器，无滤波器或锐化滤波器来抑制与其特定信道相关联的噪声。

摘要： A system having multiple arbiters is constructed to reduce the chances of arbiters synchronizing with one another. Each arbiter includes a random process that introduces randomness into an arbitration scheme performed by the arbiter. Because of the randomness, the arbiters will not tend to synchronize with one another, even when receiving an identical stream of input values.
摘要翻译：构造具有多个仲裁器的系统以减少仲裁者彼此同步的机会。每个仲裁器包括随机过程，其将随机性引入由仲裁器执行的仲裁方案。由于随机性，即使接收到相同的输入值流，仲裁者也不会相互同步。
