Abstract: Within a networking device, packet portions from multiple PDRSDs (Packet Data Receiving and Splitting Devices) are loaded into a single memory, so that the packet portions can later be processed by a processing device. Rather than the PDRSDs managing and handling the storing of packet portions into the memory, a packet engine is provided. The PDRSDs use a PPI (Packet Portion Identifier) Addressing Mode (PAM) in communicating with the packet engine and in instructing the packet engine to store packet portions. The packet engine uses linear memory addressing to write the packet portions into the memory, and to read the packet portions from the memory.
