Field programmable general purpose interface adapter for connecting peripheral devices within a computer system

摘要

A peripheral circuit interface adapter for a computer system is defined whose function is established programmatically rather than being designed, laid out and fabricated uniquely for each different function the interface adapter might perform. A designer can program the interface adapter function and then cause that function to be defined dynamically through downloading on the interface adapter when the system on which it resides is powered on. The interface adapter contains rudimentary bus interface elements and external interface section and a control section. The control section establishes the overall function of the adapter and is defined by a field programmable gate array that assumes specific wiring characteristics as a result of downloading from the hosting system.
