Nowadays by extensive application of Internet and online tools, security has become a major concern for computer system designers. The network security and prevention of the enemy intrusion and access to sensitive information are based on the cryptographic algorithms which require complex processing and fast computations. Therefore, computer arithmetic and finding 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. 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 innovation of this research is presenting the structure of a forward converter to transform inputs into residues in the OneHot format. The proposed structures have been implemented and their performance has been analyzed and evaluated.
