The embodiment of the invention discloses a data processing circuit, an automatic driving domain controller and an automatic driving vehicle. The data processing circuit comprises a plurality of processing units; wherein the plurality of processing units are annularly interconnected based on an Ethernet protocol through the Ethernet protocol switching circuit so as to form a first data path; the plurality of processing units are in star interconnection based on the PCIe protocol through the PCIe protocol exchange circuit to form a second data path. The data processing circuit provided by the invention comprises a plurality of processing units, not only can annular interconnection based on an Ethernet protocol through an Ethernet protocol switching circuit to form a first data path, but also can star interconnection based on a PCIe protocol through a PCIe protocol switching circuit to form a second data path. The first data path and the second data path are redundant to each other, so that the reliability is higher.

    本发明实施例公开了数据处理电路、自动驾驶域控制器和自动驾驶车辆。该数据处理电路包括多个处理单元;其中,该多个处理单元通过该以太网协议交换电路基于以太网协议环形互连,以形成第一数据通路;该多个处理单元通过该PCIe协议交换电路基于PCIe协议星形互连,以形成第二数据通路。本申请提供的数据处理电路,包括有多个处理单元,既可以通过以太网协议交换电路基于以太网协议环形互连,以形成第一数据通路,还可以通过PCIe协议交换电路基于PCIe协议星形互连,以形成第二数据通路,该第一数据通路和该第二数据通路互为冗余,可靠性更高。
