ABSTRACT:
A method and apparatus for emulating circuitry in a computer system is described. The method and apparatus includes a method and apparatus for determining when the circuit is to be accessed. Furthermore, in the currently preferred embodiment, the present invention includes a method and apparatus for trapping the address and data of the access. The present invention also includes a method and apparatus for generating an interrupt transparently indicating to the computer system that the circuitry is being accessed. The present invention also includes a method and apparatus for handling the interrupt and emulating the function of the circuitry. In the currently preferred embodiment, the method and apparatus for emulating comprises a software routine.
