Abstract
A programmable logic device architecture incorporating a cross-bar switch is disclosed. In a preferred embodiment, a plurality of logic cells is programmably interconnected to form an array of logic cells capable of implementing complex logic functions. A user selectable cross-bar switch block having dedicated programmable connectors is coupled to the array of logic cells by way of a mode control circuit switch. The mode control circuit switch is arranged to couple the dedicated cross-bar switch block to the array of logic cells in a first mode and to de-couple the cross-bar switch block from the array of logic blocks in a second mode.
