Ethernet MAC, 10/100 Mb, 1/10Gb (MorethanIP)

支持器件系列

• Virtex-5 LXT

The AnySpeed MAC from MorethanIP provides, with a single IP core, a solution for ethernet applications (line card, NIC card or switching) operating at 10/100/1000Mbps (gigabit ethernet) or 10000Mbps (10 gigabit). The AnySpeed MAC, together with the MorethanIP 1000 / 2500Base-X PCS core can also be used to implement proprietary or industry standard 2.5Gpbs ethernet links. The AnySpeed MAC Core operates full duplex mode, supports transparent (for switching applications) and ethernet frame termination / generation (for NIC or line cards applications) with padding and wire speed CRC check / generation.

关键特性

• Full MAC layer and reconciliation sub-layer implementation compliant with IEEE802.3ae specification
• Dynamically configurable to support 10 gigabit ethernet, with XGMII interface, gigabit, 2.5Gbps with 16-Bit eGMII (Extended GMII) interface
• Simple 64-Bit client FIFO interface
• Dynamic inter packet gap (IPG) calculation for WAN applications
• Deficit Idle Counter (DIC) for optimized performance with minimum IPG for LAN applications
