Abstract
A method and apparatus for routing data between bus devices, where each bus device is connected to a centralized switch via a point-to-point bus connection. The plurality of point-to-point bus connections collectively form a system bus. After a command is issued on the system bus, each bus device responds to the issued command by transmitting an address status response to a response combining logic module. The response combining logic module identifies which of the bus devices responded with a positive acknowledgment to the issued command, then forwards a device identifier of the bus device responding with the positive acknowledgment to the switch. The switch uses the device identifier returned via the response combining logic to route the data transfer associated with the issued command.
