Abstract

An electronic system is provided which includes a number of components. Each component includes one or more integrated circuits. During normal operation of the system, each integrated circuit provides individual operating functionality for its respective component. At least one of the integrated circuits is installed as a generic integrated circuit capable of providing any one of a number of potential operating functionalities. The generic integrated circuit is arranged to determine where in the system it has been installed upon system initialization, and, based upon the determination, configure itself to provide the required individual operating functionality for normal operation of the system.
