Abstract:
1. A communications system for enabling extension of an internal common bus architecture (CBA) bus segment of a first physical semiconductor chip device to an internal CBA bus segment of a second external physical semiconductor chip device comprising: a first serial communications interface module in said first semiconductor chip device of varying bit width at transmit and receive pins coupled to said internal bus segment of said first semiconductor chip device for serializing bus transaction from said first device to an output port of said first device; a second serial communications interface module in said second semiconductor chip external device of varying bit width at transmit and receive pins coupled to said internal bus segment for said second semiconductor chip device for de-serializing data received at an input port for said second device for providing an extension of said internal CBA bus segment in said second device to external physical devices at an input port and an external serial connector for transferring the serialized transaction between first and second devices at said input and output ports using semiconductor chip protocols; said modules carrying CBA bus commands, interrupt and confimiration operations in band over the same transmit and receive pins.
