Data processing apparatus and method using FIFO device

摘要

In a data processing apparatus and method using a first-in first-out (FIFO), the data processing apparatus includes a first sampling circuit, a delay circuit, and a FIFO device. The first sampling circuit samples a logic state of input data in response to a first edge of a first clock signal and holds a result of the sampling. The delay circuit receives and delays the first clock signal by a predetermined delay time and outputs a second clock signal. The FIFO device processes the result of the sampling output from the first sampling circuit using a FIFO method in response to a first edge of the second clock signal output from the delay circuit.
