HIGH PERFORMANCE RCA FOR VLSI DESIGN

In this Manuscript discuss the High-performance Ripple Carry Adders (RCAs) in digital logic circuits design with uses of Addition forms the basis for many processing operations, from ALUs to address generation to multiplication to filtering. As a result, adder circuits that add two binary numbers are of great interest to digital system designers. An extensive, almost endless, assortment of adder architectures serves different speed/power/area requirements. This section begins with half adders and full adders for single-bit addition. It then considers a of ripple carry adders (RCAs) for the addition of multibit words in digital logic design and systems. In this paper to discuss the RCAs performance of Synthesis RTL architecture namely SLICES, LUT and IOBs using Xilinx ISE Design Suite 12.2. In addition with Testing of RCAs 32, 64 bit adder's waveform generation using Mentor Graphics Tool Model Sim. And compare different digital words bit like 16, 32, and 64 bit in the performance of device area and timing analysis using Xilinx FPGA.
