"Features
Full media access control (MAC) layer and reconciliation sub-layer implementation compliant with IEEE 802.3ae and IEEE 802.3z specifications
Dynamically configurable to support 10-Gigabit Ethernet with XGMII interface or Gigabit Ethernet with GMII interface applications
Can be configured for NIC applications or switching/bridging applications
Lane, data alignment, PHY error, and local/remote fault signaling handled by the core's reconciliation sub-layer
CRC-32 checksum at full speed using a multistage cyclic redundancy check (CRC) calculation architecture with optional forwarding of the FCS field to the user application
Optional MAC address comparison on receive and overwrite on transmit for NIC applications
Selectable promiscuous frame receive mode and transparent MAC address forwarding on transmit
Optional multicast address filtering with 64-bin hash code look-up table (LUT) on receive reducing processing load on higher layers
Optional Ethernet pause frame (802.3 Annex 31A) termination providing fully automated flow control without any user application overhead
Optional automatic pause frame generation from programmable FIFO congestion thresholds or by dedicated command pin with programmable quanta
Programmable frame maximum length providing support for any frame (e.g., jumbo frame or any tagged frame)
Support for VLAN tagged frames according to IEEE 802.1Q specification in both transmit and receive
Dynamic packet gap (IPG) calculation for WAN applications
Deficit idle counter (DIC) for optimized performance with minimum IPG for LAN applications
Clock and data rate decoupling with programmable asynchronous FIFO buffers
64-bit user application interface compatible with Altera® Atlantic® SOC (system-on-a-chip) interface
Optional 802.3 basic and mandatory managed objects statistic counters and IETF Management Information Database (MIB) package (RFC2665) and Remote Network Monitoring (RMON) counters
Description
The programmable AnySPEED Ethernet MAC from MorethanIP provides, with a single IP core, a solution for Ethernet applications (line card, NIC card, or switching) operating at 10/100/1000 Mbps (Gigabit Ethernet) or 10,000 Mbps (10 Gigabit). The AnySPEED MAC Core operates in full duplex mode, supports transparent (for switching applications) and Ethernet frame termination/generation (for NIC or line card applications) with padding and wire speed CRC check/generation.
The core can seamlessly connect to any industry-standard Ethernet PHY devices via a Gigabit Medium Independent Interface (GMII for 1000-Mbps application), Medium Independent Interface (MII for 10/100-Mbps applications), 10-Gigabit interface, and to a user application via a 64-bit SOC interface which provides seamless connectivity to any MorethanIP cores such as Flexbus, POS-PHY L4, or third party cores, such as PCI-Express interfaces, which implement an interface compatible with the Altera Atlantic specification."
