Introduction
For industrial automation application, the IEEE 1588 standard is becoming the main
technology for precise time synchronization on Ethernet networks. This provides accurate
clock synchronization for distributed control nodes to overcome one of the drawbacks of
Ethernet.
The programmable 10/100 Ethernet MAC with IEEE 1588 integrates a standard IEEE
802.3 Ethernet MAC with a time-stamping module.
44.1.2 Features
The MAC-NET core includes the following features.
44.1.2.1 Ethernet MAC Features
• Implements the full 802.3 specification with preamble/SFD generation, frame
padding generation, CRC generation and checking
• Dynamically configurable to support 10/100 Mbps operation
• Supports 10/100 Mbps full duplex and configurable half duplex operation
• Compliant with the AMD magic packet detection with interrupt for node remote
power management
• Seamless interface to commercial ethernet PHY device via:
• a 4-bit Medium Independent Interface (MII) operating at 25 MHz, or
• a 2-bit Reduced MII (RMII) operating at 50 MHz.
• Simple 64-Bit FIFO interface to user application
• CRC-32 checking at full speed with optional forwarding of the frame check sequence
(FCS) field to the client
• CRC-32 generation and append on transmit or forwarding of user application
provided FCS selectable on a per-frame basis
• When operating in full duplex mode
• Implements automated pause frame (802.3 x31A) generation and termination
providing flow control without user application intervention
• Pause quanta used to form pause frames, dynamically programmable
• Pause frame generation additionally controllable by user application offering
flexible traffic flow control
• Optional forwarding of received pause frames to the user application
• Implements standard flow-control mechanism
• In half-duplex mode, provides full collision support, including jamming, backoff, and
automatic retransmission
• Support for VLAN-tagged frames according to IEEE 802.1Q
• Programmable MAC address: Insertion on transmit; discards frames with
mismatching destination address on receive (except broadcast and pause frames)
