ABSTRACT:
Dynamic logic counting circuits are disclosed using recirculating latched memory stages having parallel shift circuits operating in synchronism with the latch circuits to control stepping of the counts. An alternate embodiment employs steering circuit controlled subcounters, each subcounter having a parallel shift circuit operating in synchronism with its respective subcounter to step the next succeeding subcounter when its respective subcounter reaches a predetermined count such as 9 for a binary coded decimal counter or 15 for a binary counter.
