Programmable logic units are described. A described unit includes one or more first logic elements that are individually programmable to be one of a plurality of first functions; one or more second logic elements that are a decoder; one or more third logic elements that are individually programmable to be one of a plurality of second functions; and a programmable interconnect array that selectively forms one or more interconnections within a group including the logic elements, one or more input interfaces, and one or more output interfaces. The array is programmable in routing one or more input signals to at least a portion of the logic elements, routing one or more intermediate signals among at least a portion of the logic elements, and routing one or signals from at least a portion of the logic elements to produce one or more output signals via the output interface.
