ABSTRACT:
A socket for mounting an external integrated circuit on a printed circuit board is described. The socket includes a base having a bottom that can be mounted on the printed circuit board and a top that can receive the external integrated circuit. A plurality of connectors are located on the top of the base for coupling to the external integrated circuit. An in-socket embedded integrated circuit is embedded inside the base for providing a predetermined electronic function. The external integrated circuit and the in-socket embedded integrated circuit occupy substantially minimized space on the printed circuit board. The external integrated circuit can be a microprocessor and the in-socket integrated circuit can also include a microprocessor. The socket can be used for a computer system that allows the embedded microprocessor functioning when the external microprocessor is not coupled to the plurality of connectors of the base. When the external microprocessor is coupled to the plurality of connectors of the base, the computer system can be either a multiprocessor system or a single processor system with only the external microprocessor functioning. An in-socket embedded interfacing circuit is also embedded inside the base for interfacing the external microprocessor with circuitry on the printed circuit board. A single socket upgradable computer system is also described.
