The present invention discloses an asynchronous first-in-first-out cell, wherein modified Muller C elements are used to reduce the complexity of the circuit of the asynchronous first-in-first-out cell; the asynchronous first-in-first-out cell of the present invention not only can be reusable, but also can apply to a single-supply-voltage system with a single clock frequency or multiple clock frequencies and a multiple-supply-voltage system with a single clock frequency or multiple clock frequencies. Further, when the asynchronous first-in-first-out cell of the present invention is applied to the interface circuit of a dual-supply-voltage 16-point radix-22 GALS-based FFT architecture, considerable power saving and latency reduction can be achieved.
