Design residue number system components based on OneHot coding

Nowadays by using more and more Internet and online tools, security has become a major concern for computer system designers. The basis of security, prevention of intrusion, and enemy access to sensitive information is cryptographic algorithms which require complex processing and fast computations. Therefore, computer arithmetic and investigating new methods to improve basic operations such as addition, subtraction and multiplication is of great importance. In digital systems, low-delay computations play an important role, and using a residue number system is one of the ways that can speed up computational operations by parallelizing and reducing the carry propagation chain. In addition, OneHot coding, with its special features, is well compatible with the residue number system to help speed up operations by eliminating the carry propagation. In addition, with the limited changes of input in OneHot coding, the rate of circuit switching is reduced, resulting in reducing a dynamic power consumption comparing with a binary coding system. Therefore, in this article, in order to take advantage of the benefits of OneHot coding in the residue number system, the required components are designed, including adder, subtractor, and multiplier of modules with OneHot coding. The structure of a forward converter to transform inputs to residues in the OneHot format has also been introduced for the first time. The proposed structures have been implemented and have been analyzed and evaluated to investigate their performance.
