A multiplier is an electronic circuit used in digital electronics, such as a computer, to multiply two binary numbers. It is built using binary adders. A variety of computer arithmetic techniques can be used to implement a digital multiplier. Multipliers play a key role in the present digital signal handling and different applications. With advances in innovation, numerous scientists have attempted and are endeavouring to structure multipliers which offer both of the following plan targets – high speed, low power utilization, consistency of design and henceforth less zone or even mix of them in one multiplier in this way making them appropriate for different high speed, low power and minimal VLSI usage. This paper proposed proposed 64 bit ROBA multiplier with improved performance then previous. Previous work, designed only 16 bit and 32 bit ROBA multiplier. Proposed 64-bit ROBA multiplier reduced 10% area than existing 32-bit multiplier, save 60% power. Proposed multiplier is giving 5% more accuracy than existing. Delay is significant constant so it can be say that it is improved than previous. The simulation is performed Xilinx 14.7 software.
