The PCI-739 is an Intelligent Gigabit Ethernet Controller that is used to assist the host processor with LAN processing in embedded and real time systems. The PCI-739's 80321 XScale architecture, coupled with a fast memory subsystem and PCI-X busses and an efficient zero copy TCP/IP stack, rapidly processes TCP/IP, time stamping, or security functions. The PCI-739 is applied in demanding embedded LAN applications including seismic exploration, medical imaging and video-on-demand.
