Generic System Socket for Processor and Bus Devices

      This article describes a method for increasing the flexibility
of a system by providing a generic socket connection to the system
bus.  The method minimizes impact on electrical and physical design
constraints.

      Electrical and physical design constraints limit the number of
processors and other devices that can be attached to a common system
bus.  This is especially true in multiprocessor systems, where bus
loading and printed circuit board space limitations are of particular
concern.  A generic socket connection (or any interconnect method) to
the system bus significantly increases the flexibility of a system by
allowing processors and other system bus attached devices to use a
common system bus connection point, while helping the designer to
meet electrical and physical design requirements.  Each generic
system socket can accept any device compatible with the system bus.

      One or more generic system sockets can be provided on a system.
All signals required by the processor and other supported system bus
devices are routed to the system socket.  An interposer card is used
to interface the processor or bus device's footprint to the system
socket footprint.  As an example, a system may contain two processors
and one system socket.  The system socket could be used as an upgrade
path to a third processor, or to provide a graphics card, or I/O
interface.
