R. D. Kharadkar, Nagnath B. Hulle · 2015
Modulo (231-1) adder is one of the important module in ZUC stream cipher. The paper presents compact, high performance architecture for modulo (231-1) adder using CLA. The proposed architecture is implemented by using VHDL language with CAD tool Xilinx ISE Design Suite 13.2 and target device is Xilinx Spartan3-xc3s1000, with package FG320. Presented result shows that proposed architecture minimizes the chip area, power consumption and increases computation speed of modulo (231-1) adder.
