Semiconductor Technology and multimedia communication has been developed to interest in high quality video and multi channels audio. Especially, it is trend to important technology so that DVD market grows rapidly. Mpeg audio standard is available support for any bit rate. In this paper, the design of Field Programmable Gate Array(FPGA) is presented mpeg audio synthesis filter by Distributed Arithmetic Look Up Table(DALUT) method. In order to design for high speed filter that operated from 10MHz to 30MHz and DALUT is used instead of multiplier. In this paper, the output is designed by VHDL and is verification using C language. VHDL simulation used Model-sim SE 5.7f and synthesis is used Synplify Pro 7.2Ver. Target library is used XC4010E, XC4020EX, XC4052XL and P&R tool used XACT M1.4.
