Reprogrammable interconnect architecture using fewer storage cells than switches.

摘要

A first user re-programmable interconnect architecture is provided wherein N switching elements are connected between selected interconnect conductors. The switching elements are controlled by M active storage elements, where M<N. A group of N switching elements are controlled by a group of M active storage elements, where M<N. The states of the M active storage elements are collectively decoded to identify the one of N switching elements to be turned on. A second user re-programmable interconnect architecture is provided wherein a group of N switching elements are connected between selected interconnect conductors and are partially selected by decoding the states of m1 active storage elements. The group of N switching elements are also partially selected by decoding the states of m2 active storage elements. The decoding is arranged such that t the states of m1 and m2 active storage elements each are decoded to provide a partial address to identify one of the N switching elements to be turned to its "on" state. The sum of m1 and m2 is less than N. <IMAGE>
