Latest Patents

One of his latest patents is for an "Automotive network switch with attack protection." This invention involves a network switch designed for use in an Ethernet network within a vehicle. It features multiple ports, a switch unit, a peripheral bus, multiple DMA engines, and a mapping engine. The ports connect to the Ethernet network, while the switch unit is responsible for forwarding packets among the ports. The peripheral bus connects to a host that runs host applications, and the DMA engines facilitate the transfer of packets from the host applications to the switch unit. The mapping engine constructs a mapping that ensures packets are forwarded only after verifying that the DMA engine transferring the packet is correctly mapped to the bus function assigned to the host application.

Another significant patent is for a "Network switch with DMA controller for independent direct memory access of host system." This invention includes a data bus, a register, an endpoint controller, and a direct memory access controller. The endpoint controller receives a descriptor generated by a device driver of a host system and stores it in the register. It also transfers data between a root complex controller of the host system and the data bus. The direct memory access controller independently controls the transfer of data between the memory of the host system and a network device connected to the network switch.
