Abstract
Abstract Disclosed is a digital device on a semiconductor chip, which is comprised of a plurality of storage means for storing digital signals therein, a plurality of functional means for performing functional operations on the digital signals, and an interconnect matrix. The matrix includes a plurality of input busses connected to receive signals from the storage means and the functional means, and a plurality of output busses connected to send signals to the storage means and functional means. The interconnect matrix further includes N sets of selectable electrical contacts where N is any positive integer. Each set selectively intercouples the input busses to the output busses in various parallel paths. Signals are transferred between the input and output busses through any one set of the N sets of electrical contacts in response to N respective control signals.
