ABSTRACT:
Delay in a clocked logic circuit is reduced by partially determining a next state of the clocked logic circuit based on a current state of the clocked logic circuit during a first portion of a clock cycle. The partially determined next state of the clocked logic circuit is prevented from affecting the current state of the clocked logic circuit during the first portion of the clock cycle. The next state of the clocked logic circuit is completely determined based on a previous state of the clocked logic circuit and the partially determined next state of the clocked logic circuit during a second portion of the clock cycle.
