Patent abstract
A host-daughtercard interface is pin compatible with a legacy interface but redefines a subset of pins to implement a high-bandwidth double data-rate (DDR) bus. By inspecting a cookie on the daughtercard, the host platform determines whether the daughtercard supports the DDR bus or the legacy interface, and then configures the subset of pins to implement the legacy interface or the DDR bus.
