    Abstract: A universal array logic module featuring autonomous operation includes interconnected array structured logic and a small writable storage array. The module is subject to large scale integrated packaging as a standardly dimensioned unit (e.g. chip). The internal connections form discrete first and second internal circulation loops in one of which the storage array connects as a serial constituent randomly addressable by signals carried in the other loop. The storage array typically holds eight 32-bit words. The logic arrays may be read-only structures organized to perform arithmetic and translational logic manipulations under autonomous (internal) control. The module assembly includes integral input/output gating for transferring signals between an external bus and the internal loops. The logic array structure permits both external and internal control of cyclic operation. The operation repertoire includes interrupts, resets, and sequence branches. Interrupted status (loop signals) is saved in predetermined address locations of the storage array, requiring novel manipulation and storage of the address argument of the interrupted cycle. The logic arrays may be economically configured as read-only structures.
