Efficient half-cycle clocking scheme for self-reset circuit

摘要

A pipelined domino architecture includes pairs of pipeline stages each comprising a first active clocked stage and a number of subsequent self-reset logic gates. Each pipeline stage is clocked by one or the other of a clock signal. Each active clocked stage and self-reset logic gate of any particular pipeline state includes a reset circuit to reset the output of such stage or gate at the conclusion of an evaluation period that is initiated by a phase of the clock signal. Only the active clocked stage is clocked; the self-reset logic stages rely upon the reset of the output of the active clocked stage to generate the necessary reset signals that will reset their respective outputs.
