Design and Implementation Of Modulo Multiplication by Using Radix-8 and Prefix adders

Supriya Sarkar , G.Dilip , Sanghita Deb

The residue number system (RNS) has emerged as a promising alternative number representation for the design of faster and low power multipliers owing to its merit to distribute a long integer multiplication into several shorter and independent modulo multiplications. This modulo multiplication is frequently used in digital processing systems at the encryption and decryption of PKC(public key cryptography) algorithms are performed by repeated modulo multiplications these multiplications differ from those encountered in signal processing and general computing applications. In this method we are using radix-8M.B.E technique for partial product generator and modulo addition by prefix adders. It is over comes the previous methods delay problem.
