Special interconnect for configurable logic array

A configurable logic array comprising:

• a plurality of configurable logic elements (CLEs), each CLE having at least one input lead and at least one output lead;
• a general interconnect structure comprising a plurality of general interconnect leads and a plurality of programmable general interconnect junctions for interconnecting selected ones of said general interconnect leads;
• one or more input access junctions for each input lead, each of said input access junctions being programmable for connecting a corresponding general interconnect lead to said input lead;
• one or more output access junctions for each output lead, each of said output access junctions being programmable for connecting said output lead to a corresponding general interconnect lead;
• means for programming said general interconnect junctions and said access junctions to provide an electrical path connecting one of said at least one output lead of one of said plurality of CLEs to one of said at least one input lead of one of said plurality of CLEs, said electrical path containing two access junctions and at least a portion of one of said general interconnect leads;
• and
• at least one special interconnection circuit which permits a selected output lead of one of said CLEs to be connected to a selected input lead of another CLE, said special interconnection circuit not containing any portion of the general interconnect leads or any junction in the general interconnect structure.
