Abstract: A distributed computing system in an autonomous driving vehicle (ADV) includes a main compute system and multiple subsystems, and a bus structure that connect the main compute system and the multiple subsystems. The bus structure provides uniform system-to-system connectivity. A host field-programmable gate array (FPGA) agent coupled to the main compute system can communicate with slave FPGA agents on the subsystems via multiple pairs of bus interface protocols of a particular type. The bus interfaces on the FPGA agents supports the uniform system-to-system connectivity.
