Product Details

The Intel 82571EB Gigabit Ethernet Controller for PCI Express is designed for high performance and low memory latency. The device is optimized to connect to a system Memory Control Hub (MCH) using up to four PCI Express lanes.

Alternatively, the controller can connect to an Input/Output (I/O) Control Hub (ICH) that has a PCI Express interface. Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and data words.

Combining a parallel and pipelined logic architecture optimized for Gigabit Ethernet and for independent transmit and receive queues, the controller efficiently handles packets with minimum latency.

The Intel® 82571EB Gigabit Ethernet Controller is a single, compact component with two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports.

Features

  • Advanced interrupt-handling features and uses
  • Efficient ring-buffer descriptor data structures
  • Up to 64 packet descriptors cached on chip. A
  • Large 48 KByte per port on-chip packet buffer
  • Controller offloads tasks from the host, such as checksum calculations for transmission control protocol (TCP), user datagram protocol (UDP), and Internet protocol (IP); header and data splitting; and TCP segmentation.
