    • A server-proxy-client network delivers web content objects from servers to clients from cache content at a proxy server in between. Multiple, moving-window buffers are used to service content requests of the server by various independent clients. A first request for content is delivered by the server through the proxy to the requesting client. The content is simultaneously duplicated to a first circulating buffer. Once the buffer fills, the earlier parts are automatically deleted. The buffer therefore holds a most-recently delivered window of content. If a second request for the same content comes in, a check is made to see if the start of the content is still in the first buffer. If it is, the content is delivered from the first buffer. Otherwise, a second buffer is opened and both buffers are used to deliver what they can simultaneously. Such process can open up third and fourth buffers depending on the size of the content, the size of the buffers, and the respective timing of requests.
    • 服务器 - 代理 - 客户端网络从服务器到客户端之间的代理服务器的缓存内容传送Web内容对象。 多个移动窗口缓冲区用于为各种独立客户端的服务器的内容请求提供服务。 内容的第一个请求由服务器通过代理传递给请求客户端。 内容同时复制到第一循环缓冲器。 一旦缓冲区填满,早期的部件将被自动删除。 因此,缓冲区拥有最近发布的内容窗口。 如果对相同内容的第二个请求进入,则检查内容的开始是否仍在第一个缓冲区中。 如果是,内容是从第一个缓冲区传递的。 否则,打开第二个缓冲区,并使用两个缓冲区来同时提供它们。 该过程可以根据内容的大小,缓冲器的大小以及各个请求的定时来打开第三和第四缓冲器。

    • A multiple layer mesh design that provides that a bridge associated with a second layer connects a rail on a first layer to a trunk on a fourth layer. If the trunk on the third layer shadows a plurality of rails on the first layer, preferably the bridge is at least as wide as a sum of the widths of the rails on the first layer which are shadowed by the trunk on the third layer. If the trunk on the third layer shadows a single rail on the first layer, preferably the bridge is at least as wide as twice the width of the rail on the first layer.

    • A baud rate acquisition circuit (10) for synchronizing a sampling signal with an input signal operates in broad rate sweeping and a rate fine tuning phases. In the rate sweeping phase, a timing error detector (24) examines the sampling signal generated by a decimator (16). If the sampling signal is outside a rate acquisition range from the target rate, a rate sweeping algorithm selects a new sampling rate. In response to the sampling rate within the rate acquisition range, the timing error detector (24) examines the asymmetry thereof to generate a rate correction signal to synchronize the sampling signal with the input signal. Next in the rate fine tuning phase, a multiplexer (22) routes the sampling signal through a square root filter (18). By examining the waveform shaped signal, the time error detector (24) synchronizes the sampling signal with the input signal with high accuracy.
    • 用于使采样信号与输入信号同步的波特率采集电路(10)以广泛的频率扫描和速率微调相位工作。 在速率扫描阶段中,定时误差检测器(24)检查由抽取器(16)产生的采样信号。 如果采样信号在目标速率以外的速率采集范围之外,则速率扫描算法选择新的采样率。 响应于速率采集范围内的采样率,定时误差检测器(24)检查其不对称性,以产生速率校正信号,以使采样信号与输入信号同步。 接下来在速率微调相位中,多路复用器(22)将采样信号通过平方根滤波器(18)。 通过检查波形信号,时间误差检测器(24)以高精度同步采样信号与输入信号。

    • Input data at a first resolution are received from a source. The input data are compressed. The input data can be downsampled to generate compressed downsampled data at a reduced resolution. The compressed downsampled data can be used to generate a frame at the reduced resolution. When the frame is needed as a reference for another frame, the compressed downsampled data can be decoded to generate decompressed downsampled data at the reduced resolution. Motion compensation is performed on the decompressed downsampled data at the second resolution to generate motion compensated decompressed downsampled data used as a reference for a second frame. Thus, by performing motion compensation on downsampled data directly, data processing operations such as transcoding can be accomplished quickly and effectively while saving computing resources.
    • 从源接收第一分辨率的输入数据。 输入数据被压缩。 可以对输入数据进行下采样,以降低分辨率产生压缩的采样数据。 压缩的下采样数据可以用于以降低的分辨率生成帧。 当需要帧作为另一帧的参考时,可以对压缩的下采样数据进行解码,以降低分辨率产生解压缩的下采样数据。 以第二分辨率对解压缩的下采样数据执行运动补偿,以产生用作第二帧的参考的运动补偿解压缩下采样数据。 因此,通过直接对下采样数据执行运动补偿,可以在节省计算资源的同时快速有效地实现诸如转码的数据处理操作。
