摘要
Methods and apparatuses relating to circuitry for multilane serial bus communications are described. In an embodiment, an apparatus includes a serial bus controller, upstream serial bus lanes, a single downstream serial bus lane, and a host/device lane controller. The serial bus controller is to send and receive data transmissions to and from serial bus devices. The upstream serial bus lanes correspond to the serial bus devices and are associated with serial port addresses. The host/device lane controller is to receive data transmissions through the upstream serial bus lanes and includes a port address assignment circuit and a multiplexer. The port address assignment circuit is to assign serial port addresses to data transmissions, to be included in data transmissions to identify the upstream serial bus lanes through which the data transmission was received. The multiplexer is to forward data transmissions from upstream serial bus lanes to the downstream serial bus lane.
