• Routes Controller Area Network (CAN) frames to or from Ethernet interfaces using IEEE 1722 ACF frames

    • Supports different Ethernet transmit trigger modes

    • User-configured Ethernet MAC Header (Layer 2) for ACF transmit frames

    • Automatic Ethernet DMA transmit and receive descriptor handling

    • Configurable AVTP stream-ID

    • CAN-ID based CAN interface destination search

    • Filtering of CAN frames tunneled over Ethernet

    • User-configured CAN Routing Table to identify the destination CAN interface for a CAN frame tunneled over Ethernet

  • Assists CAN Routing Engine (CRE) to perform inter-MCMCAN transfer of CAN frames from a CAN interface to another CAN interface

  • Assists CRE to perform routing of received CAN frame(s) or CAN I-PDU(s) from a CAN interface to a configurable internal memory address location

    • Automatic memory address increment and wrap around

    • User-configured watermark interrupt generation for CPU notification

  • Supports 1:1 uni-cast routing and 1:4 multi-cast Ethernet to CAN routing

  • Provides non-starving arbitration between routing transfer requests

  • Supports 1:1 uni-cast or 1:6 multi-cast forwarding of Ethernet frames between interfaces

  • Provides non-starving arbitration between routing and forwarding requests

  • Provides error monitoring mechanisms for accelerated detection of faults
