ABSTRACT

In this Manuscript to discuss the High valuable Ripple Carry Adders (RCAs) in digital logic design circuits with Addition algorithm forms the basis for many digital processing operations, from MAC and ALUs to address generation. As result, adder digital circuits that add two binary digits are of great interest to digital system designers. Almost endless the adder structure requirements different speed/power/area requirements. Also this section begins with half adders and full adders for single-bit addition. Then considers of ripple carry adders (RCAs) for the addition of 32-bit multibit words in digital logic design and systems. In this manuscript to discuss the RCAs performance of Synthesis RTL architecture namely SLICE, look up table (LUT) and input and output Blocks (IOBs) using Xilinx ISE Design Suite 12.2. In addition with Testing of RCAs 16 and 32-bit adder’s waveform generation using Xilinx ISE Design Suite 12.2. And compare different digital words bit like 16-bit and 32-bit in the performance of device area and timing analysis using Xilinx FPGA.
