In this brief, the implementation of efficient image encryption and decryption scheme in Residue Number System (RNS) is analyzed. The RNS domain is mainly chosen for its carry free parallel and fast arithmetic operations. But, the converters make RNS inefficient by having large delays. Hence, to use the RNS for our applications we must have the efficient converters. Here, we designed pure combinational...
VLSI, in modern day technology has seen extensive use of PPA with a better delay performance. These pre-compute the carries and thus have upper hand over the commonly used Ripple Carry Adder (RCA). Addition has been an indispensible operation in most of the widely used applications. We present the 4,8,16 and 32 bit of different adders-Carry Look Ahead (CLA), Carry Save Adder (CSA), Kogge Stone Adder...
