PROGRAMMABLE MULTIPLEXING INPUT/OUTPUT PORT

摘要

An input/output port design for integrated circuits which improves communications bandwidth. Through multiplexing techniques the design creates virtual input/output pins (40, 41) while utilizing a single physical pin (44, 45). The virtual pins improve the communications bandwidth while minimizing the physical design of the integrated circuit. The invention can be utilized in a variety of integrated circuits, including programmable logic devices and field programmable gate arrays (14).
