CORE: Core module interconnects all the sub-modules in the Ethernet 100G MAC IIP . Ports of core module are the top level ports for the Ethernet 100G MAC IIP.

TX-CTRL: Transmit Control block processes the data from system interface/AXI-interfaces and push the data into Transmit FIFO.

TX_FIFO : TX ASYNC FIFO module stores TX data and processes it with the different read and write clock domain.

Transmit MAC TX-FSM: The transmit FSM receives the data from MAC client and maps them to the MAC 100G Interface by encapsulating the Ethernet packet and frame headers.

RX-CTRL: RX Control block processes the data from MAC 100G interface and push the data into Rx ASYNC FIFO.

RX_FIFO : RX ASYNC FIFO module stores Rx data and process the data with the different read and write clock domain.

Receive MAC RX-FSM: The Receive FSM receives the data from underlying physical layer and sends them to MAC client by decapsulating the Ethernet Packet headers.

FLOW CTRL: Initiating the Transmission of pause frame-based on the Receive FIFO's threshold or External requests.

PAUSE_TIMER: Implements the Pause timer logic based on the Pause Quanta Value.

LINK FAULT FSM: The Link Fault FSM module indicates the RX and TX link status, the local fault signal indicates by PHY layer.when the local fault signal reached the RS layer, the RS continuously generate the remote fault signal on CGMII TXD and TXC output signal

MDIO: The MDIO Master serial interface is used to control the PHY registers with read and write frames

CSR: CSR Module has all the configurable registers. The contents of the registers are decoded and assigned to its respective output ports based on its functionality.
