Abstract

One embodiment of the present invention provides a state machine that receives as input a clock signal and determines a frequency relationship between circuits. The state machine generates outputs that control buffer circuits. The buffer circuits latch signals input to them until the output signals from the state machine cause the buffer circuits to latch new input signals. The buffer circuits are used to latch data until that data can be used appropriately.
