Adaptive Circuit Board Assembly and Flexible PCI Express Bus

摘要

A system and method for adaptive bus configuration operable to respond to hardware changes and other configuration changes is disclosed. In an embodiment, the computing system includes a circuit assembly having at least one processing resource coupled to a respective set of bus traces, at least one peripheral device socket coupled to a respective set of bus traces, and a bus switch coupled to the bus traces of the processing resource and the bus traces of the peripheral device. The bus switch implements a set of connections between the bus traces of the processing resource and the bus traces of the peripheral device sockets according to an instruction. The instruction may specify an allocation of peripheral device sockets to processing resources based on the number of installed processing resources so that no peripheral device is connected to a bus without an attached processor.
