Design of High-Speed Adder with three operands for Image Blending Applications

Adders are among the most often utilized basic electrical circuit design elements and are essential for processes like digital signal processing. The development of adders that give either quick speed, low power consumption, compact area, or a combination of these has been attempted and is still being attempted by researchers. With the help of performance indicators including area, delay, and power distribution, we compare various carry adders in this study, including the RCA, CSA, CCA, and the Adder with three operands. The 8- bit Three operand binary adder that is being proposed is quicker than the 8-bit Carry save adder, 8-bit Carry save adder, and 8-bit Ripple carry adder.
