PMC677RCTX

PMC677RCTX is a PMC designed to offer maximum 1000Mbit Ethernet connectivity. Using 10/100/1000BaseT, the PMC677RCTX is capable of full duplex operation. The Ethernet/PCI interface includes a powerful DMA engine with 64KB deep FIFO buffers. This assures continuous, full bandwidth operation with minimum PCI overhead. PMC677RCTX 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 PMC677RCTX boards can be directly cabled with a simple "cross-over". This configuration creates a full duplex 1000Mbit dedicated data path (for each port) - 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 PMC677RCTX an excellent candidate for high performance interconnects that require real time determinism. Software drivers are available for most popular operating systems including VxWorks, Linux, LynxOS, Windows NT and Solaris. These drivers have been carefully designed and implemented to fit within the LAN protocol stack of the host operating system. All facilities available from the host OS can be used across the PMC677RCTX.
