RM676 is a Gigabit Ethernet PCI NIC with dual 1000BaseSX interfaces. The card is capable of full duplex operation on each of its channels. The Ethernet/PCI/PCI-X interface includes a powerful DMA engine for each port with very deep FIFO buffers (64K byte). This assures continuous, full bandwidth operation with minimum PCI overhead. The RM676 has SC connectors. The RM676 does not have a PCI-to-PCI bridge on board. RM676 has a rich suite of host off-loading feature including: Packet filtering based on checksum errors; SNMP and RMON statistic counters; Hardware TCP checksum off-loading; and Support for various address filtering modes such as 16 exact matches (unicast or multicast), 4096-bit hash filter for multicast frames and Promiscuous unicast and multicast. Two RM676 boards can be directly cabled with a simple "cross-over". This configuration creates a full duplex 1000Mbit dedicated data path - delivering high bandwidth at very low cost. More complex, dedicated interconnects can be created using a hub or switch. Both point-to-point and switched hubs, in full duplex mode, remove many determinism concerns raised with traditional Ethernet solutions. This makes the RM676 an excellent candidate for high performance interconnects that require real time determinism. Software drivers are available for most popular operating systems including Windows, Linux, LynxOS, Vxworks and Solaris. These drivers have been carefully designed and implemented to fit within the LAN protocol stack of the host operating system. Thus all facilities available from the host OS can be used across the RM676. Solaris OBP and PXE boot options are available.
