CONTROL UNIT FOR TRANSLATING BETWEEN DIFFERENT BUS INTERFACES

Abstract

Some embodiments relate to a control unit including a Controller Area Network (CAN) interface including a plurality of serial communication ports and an Ethernet interface. A first plurality of CAN-to-Stream-identifier (ID) logic circuits are coupled to the plurality of serial communication ports, respectively. A routing table is coupled to the first plurality of CAN-to-Stream-ID logic circuits. The routing table stores a first plurality of CAN IDs and a first plurality of Stream IDs, respectively. A Stream-ID-frame-to-Ethernet-frame-generation logic has a plurality of inputs coupled to respective outputs of the first plurality of CAN-to-Stream-ID logic circuits, respectively, and has respective outputs coupled to the Ethernet interface. The first plurality of CAN-to-Stream-ID logic circuits are instantiated in a first plurality of hardware circuits, respectively.
