Arithmetic adder is the most important basic element for many digital applications. In this paper different types of adders are taken for experimental study such as Ripple Carry Adder, Carry Save adder, Carry Look ahead adder, Carry Increment adder, Carry Select adder, and Carry Skip adder. Here in this paper introducing a novel technique for designing a new Carry Select adder for multi precision...
Recently, Security requirements forelectronic transactions have become an important concern. RSA is the widely adopted public key algorithms. The RSA public key cryptography uses modular exponentiation operation both for encryption and decryption. A famous approach is Montgomery modular multiplication decreases the multiplication period dramatically. Today's system loses information after every logic...
Multipliers are the key components of systems viz. FIR filters, Microprocessors, Digital Signal Processors etc. which demands high performance. The performance of these applications mainly depends on the numbers of multiplication done in unit time. In real time multipliers the speed and power are the major criteria, thus faster and power efficient multipliers are needed. This paper focuses on the...
A very-front-end electronics dedicated to high granularity calorimeters has been designed and its performance measured. This electronics performs the amplification of the charge delivered by the detector thanks to a low-noise Charge Sensitive Amplifier. The dynamic range is improved using a bandpass filter based on a gated integrator. Studying its weighting function, we show that this filter is more...
In this paper, we propose a new design method for modulo 2a-1 multipliers which accept double representation of 0 of input operands. The new multiplier takes advantage of the symmetric properties of integers written in l's complement representation which allows to reduce the size of carry-save adders (CSAs) used. Currently, for small a they are the least complex (in terms of the number of logic gates)...
Basic operations of public key cryptography are multiplication and exponentiation. Because of long operand length, their processing is very time consuming operations. The basic of all of these operations is multi operand addition. To improve this operation's performance, many methods are used, that carry save adder (CSA) is the best method until now. This paper proposed a new method with the same...
