Introduction

The Intel

82545GM Gigabit Ethernet Controller is a single, compact component with an

integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. The

Intel

82545GM enables Gigabit Ethernet implementations in a very small area and can be used

for desktop and workstation PC network designs as well as backplane applications with critical

space constraints.

The Intel

82545GM integrates Intel’s fourth generation gigabit MAC and PHY to provide a

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

82545GM on-board System Management Bus (SMB) port enables network

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.
