AI 生成的摘要:
The autonomous CAN-FD frame-routing gateway enables efficient frame-level routing across multiple RS-CANFD units using DMA and SDMAC, supporting up to 16 CAN channels with minimal CPU involvement except for error handling. It allows selective ID routing, bit rate and protocol conversion between classical CAN and CAN-FD, and implements the Most Priority First Out (MPFO) principle for transmit queues. The gateway uses RX-FIFOs and transmit queues for message forwarding, with configurable reception rules and resource allocation to balance performance and avoid overflow. Limitations include transmit queue overflow risks when routing to slower channels and a maximum of eight destinations per message. The system supports flexible channel configurations and integrates interrupt-driven exit conditions.
