BCM5709C block diagram the BCM5709C provides a dual-port, fully integrated layer 4 and layer 5 solution - tcp/ip, rdma, and iscsi along with two complete 10/100/ 1000base-t gigabit ethernet physical layer devices, ieee 802.3 compliant media access controls (mac) and physical layer transceiver solution for high performance network applications. by itself, the BCM5709C provides a complete dual-port, single-chip gigabit ethernet nic with tcp/ip processing engine, rdma nic (rnic), iscsi hba or lom solution. the BCM5709C is different from other network controllers because it can process the tcp/ip and relevant l5 protocols on data directly from the application buffers on the host, thereby relieving the host cpu from these time-consuming operations. on the receive path, the BCM5709C processes the frame up to the highest layer supported present in it, for example, the BCM5709C processes the frame for rdma when the frame is an rdma frame. with the appropriate configuration, the BCM5709C can simultaneously support the following three functions: ? rdma network interface controller (rnic) ? iscsi host bus adapter ? toe chimney-enabled network accelerator target applications of the BCM5709C ? gigabit ethernet nics and lan-on motherboard (lom) ? iscsi host bus adapters (hba) ? rdma network interface card (rnic) clock pll led control led signals smb interface sflash interface smbus sflash control pci express ? nc-si nc-si buffer memory pci express ? x4 tcp/ip processing engine iscsi protocol offload rdma protocol engine 10/100/1000 rx tx 10/100/1000 phy tx rx memory controller 10/100/1000 mac 10/100/1000 mac phy 10/100/1000 network interface card (nic) designs dual 10/100/1000base-t pci express x4 nic lan on motherboard (lom) designs dual 10/100/1000base-t pci express x4 nic
