    • A method and structure is provided for buffering data packets having a header and a remainder in a network processor system. The network processor system has a processor on a chip and at least one buffer on the chip. Each buffer on the chip is configured to buffer the header of the packets in a preselected order before execution in the processor, and the remainder of the packet is stored in an external buffer apart from the chip. The method comprises utilizing the header information to identify the location and extent of the remainder of the packet. The entire selected packet is stored in the external buffer when the buffer of the stored header of the given packet is full, and moving only the header of a selected packet stored in the external buffer to the buffer on the chip when the buffer on the chip has space therefor.
    • 提供了一种在网络处理器系统中缓冲具有报头和余数的数据分组的方法和结构。 网络处理器系统在芯片上具有处理器和芯片上的至少一个缓冲器。 芯片上的每个缓冲器被配置为在处理器中执行之前以预先选择的顺序缓冲数据包的报头,并且数据包的剩余部分存储在与芯片分离的外部缓冲器中。 该方法包括利用报头信息来识别分组的其余部分的位置和范围。 当给定分组的存储报头的缓冲器已满时,整个所选分组被存储在外部缓冲器中,并且当芯片上的缓冲器仅将存储在外部缓冲器中的选定分组的报头移动到芯片上的缓冲器时 有空间。
