Abstract
An intelligent bus bridge contained in a single integrated circuit chip is disclosed along with computer systems and server systems that employ intelligent input/output subsystems. The intelligent bus bridge includes a local processor coupled for communication over a local component bus, a local memory controller that enables access to a local memory from the local component bus, and a component bus bridge that propagates accesses between the local component bus and a system component bus. The single integrated circuit chip enables dual-porting of the local memory controller without significant increases in input/output pins. A mode control input to the intelligent bus bridge indicates whether the intelligent bus bridge functions in a local master mode or a host master mode in a computer or server system.
