    • In an aspect, a first method of interfacing a processor and memory is provided. The first method includes the steps of (1) generating a first command and associated address of a first type that does not indicate a rank of memory targeted by the first command; (2) determining whether the memory includes a plurality of ranks; (3) if the memory includes a plurality of ranks, employing the processor to update the address associated with the first command to indicate a memory rank targeted by the first command; (4) if the memory does not include a plurality of ranks, employing the processor to update the address associated with the first command to indicate the memory does not include a plurality of ranks; and (5) converting the first command and associated updated address to a second command and associated address that are employed to access the memory. Numerous other aspects are provided.

    • A method, apparatus and computer program product are provided for implementing virtual packet storage via packet work area (PWA) in a network processor system. A mapping area including a packet work area and a corresponding set of packet segment registers (PSRs) are provided. A PSR is loaded with a Packet ID (PID) and a packet translation unit maps the packet data into the corresponding PWA. The PWA address defining an offset into the packet is translated into a physical address. The packet translation unit redirects loads and stores of the PWA into the correct data buffer or buffers in system memory. Packets include one or more data buffers that are chained together, using a buffer descriptor providing the packet physical address. The buffer descriptor points to a data buffer for the packet and to a next buffer descriptor.
    • 提供了一种用于通过网络处理器系统中的分组工作区(PWA)实现虚拟分组存储的方法,装置和计算机程序产品。 提供了包括分组工作区域和相应的分组段寄存器(PSR)集合的映射区域。 PSR装载有分组ID(PID),分组转换单元将分组数据映射到对应的PWA中。 定义到分组中的偏移的PWA地址被转换成物理地址。 分组转换单元将PWA的加载和存储重定向到系统存储器中的正确的数据缓冲器或缓冲器。 数据包包括使用提供数据包物理地址的缓冲区描述符链接在一起的一个或多个数据缓冲区。 缓冲区描述符指向数据包的数据缓冲区和下一个缓冲区描述符。
