In this design we have adopted as a FIFO shift register, through the VHDL hardware design language frequency, so that we can read and write operation have been different rates of change. In this design, we have adopted maxplux2 simulation environment, called related chip to form a complete circuit..Therefore, - a simple and reliable code transform circuit speed digital information transmission system is essential. Keywords: Code transform circuit speed, Rate of transformation, FIFO. 摘要 I
