Introduction
The Intel
integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. The
Intel
for desktop and workstation PC network designs as well as backplane applications with critical
space constraints.
The Intel
standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T
applications (802.3, 802.3u, and 802.3ab). The controller is capable of transmitting and receiving
data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps. In addition, it provides a 64-bit wide direct
Peripheral Component Interconnect (PCI) 2.3 and PCI-X 1.0a compliant interface capable of
operating at frequencies up to 133 MHz.
The Intel
manageability implementations required by information technology personnel for remote control
and alerting through the LAN. Using the SMB, management packets can be routed to or from a
management processor. The SMB port enables industry standards, such as Intelligent Platform
Management Interface (IPMI) and Alert Standard Format (ASF), to be implemented using the
82545GM. In addition, on chip ASF 1.0 circuitry provides alerting and remote control capabilities
with standardized interfaces.
The 82545GM Gigabit Ethernet Controller architecture is designed to deliver high performance
and PCI/PCI-X bus efficiency. Wide internal data paths eliminate performance bottlenecks by
efficiently handling large address and data words. Combining a parallel and pipe-lined logic
architecture optimized for Gigabit Ethernet and independent transmit and receive queues, the
82545GM controller efficiently handles packets with minimum latency. The 82545GM controller
includes advanced interrupt handling features to limit PCI bus traffic and a PCI interface that
maximizes the use of bursts for efficient bus usage. The 82545GM is able to cache up to 64 packet
descriptors in a single burst for efficient PCI bandwidth use. A large 64-Kbyte on-chip packet
buffer maintains superior performance as available PCI bandwidth changes. By using hardware
acceleration, the controller is able to offload tasks, such as checksum calculations and TCP
segmentation, from the host processor.
