Programmable logic device |
摘要 |
A programmable logic device of the present invention is constructed to reduce the number of switching elements in wire switches when programmably connecting logical elements by using wire groups. A plurality of programmable wire groups are wired in vertical and horizontal channels between logical elements arranged in array. The wire groups are combined to intersect preferably in crosses. The wire groups are short-circuit-connected at the intersections or connected through programmable switching elements. Programmable connections are effected through wire switching means middled between the wire elements provided between the adjacent intersections. Hence, the programmable logic device of this invention is capable of reducing the areas occupied by the switching elements in the switching means and attaining a high degree of freedom of wiring and a high integration.
