Continuous advances in microelectronic technologies make better use of energy, encode data more effectively, transmit more reliable information, etc. In particular, many of these technologies address low power consumption to meet the needs of various portable applications. In these application systems, a multiplier is a fundamental arithmetic unit and widely used in circuits. VHDL is one of the most common techniques for the emerging digital system process. The technique is done by the program using certain software that performs the simulation and the examination of the designed system. The designer only needs to describe his digital circuit design in textual form that he can eliminate without the effort of altering the hardware. VHDL is more preferred because this technique can reduce cost and time, easy to fix, portable, a lot of software platform support VHDL function and high availability of references. All processes will be executed using the Xilinx ISE 8.2i software, which means that the process is simulated only without hardware implementation. Multiplication is a fundamental operation in most signal processing algorithms. The multipliers have a large area, long latency and consume considerable power. Therefore, the design of the low power multiplier has been an important part in the design of the low power VLSI system. Fast multipliers are an essential part of digital signal processing systems. The speed of multiplier operation is of great importance in digital signal processing as well as in today's general purpose processors. The principle of basic multiplication is twofold, that is, the evaluation of partial products and the accumulation of displaced partial products.
