Abstract
A communications system for enabling extension of an internal common bus architecture (CBA) segment of a first root physical device to an internal CBA bus segment of one or more remote external physical device includes the first root physical device having a first serial communications interface module in the root device coupled between said internal CBA bus segment and an input and output port of the root device for serializing bus transactions from the first device to the output port of the root device and deserializing data received from at the input port to the internal CBA bus segment of the first device. The remote external physical device includes a second serial communications interface module coupled between the internal CBA bus segment and an input and output port of the remote device for serializing bus transactions from the remote device to the output port of the remote device and deserializing data received at the input port to the internal CBA bus segment of said remote device. The modules are coupled to each other by an external cabling. An enumerator in the root device obtains knowledge of the remote hardware module and accompanying register set by abstracting these details and automatically configuring the remote module in the system.
