ABSTRACT:
The invention relates to the design and operation of local clock control circuits which operate to supply a local clock signal to a controlled block of a digital circuit in response to an enable signal representative of an enable condition. The invention is embodied in several alternative local clock control circuits which comprise a signal joining means or a signal joining means in combination with an enable signal relay means. The signal joining characteristics of the Muller C-element are used advantageously in several embodiments. The invention serves to ease constraints on the arrival time of an enable signal at the local clock control circuit.
