This paper introduces novel architecture for Radix-10 decimal multiplier. The new generation of highperformance decimal floating-point units (DFUs) is demanding efficient implementations of parallel decimal multiplier. The parallel generation of partial products is performed using signed-digit radix-10 recoding of the multiplier and a simplified set of multiplicand multiples. The reduction of p...

A new FFT architecture for real-valued signal is proposed using Radix-2 algorithm. It is based on modifying flow graph of the FFT algorithm such that it has both real and complex datapaths. A redundant operation in flow graph is replaced by imaginary part. Using folding technique RFFT architecture with any level of parallelism can be achieved. This RFFT architecture will lead to low hardware co...

This paper is mainly concerned with feedback control systems governed by fractional impulsive evolution equations involving Riemann–Liouville derivatives in reflexive Banach spaces. We firstly give an existence and uniqueness result of mild solutions for the equations by applying the Banach’s fixed point theorem. Next, by using the Filippove theorem and the Cesari property, a new set of suffici...

This paper studies stability for parametric mathematical programs with geometric constraints. We show that, under the no nonzero abnormal multiplier constraint qualification and the second-order growth condition or second-order sufficient condition, the locally optimal solution mapping and stationary point mapping are nonempty-valued and continuous with respect to the perturbation parameter and...

We discuss conditions for the Aubin property of solutions to perturbed cone constrained programs, by using and refining results given in Klatte-Kummer ”Nonsmooth Equations in Optimization”, Kluwer, 2002. In particular, we show that constraint nondegeneracy and hence uniqueness of the multiplier is necessary for the Aubin property of the critical point map. Moreover, we give conditions under whi...

This paper studies the effect of high performance pipelined GF(2 256 ) bit-serial multiplier on elliptic curve point operations. A 3-stage pipelined version of the Massy-Omura GF(2 m ) normal basis multiplier for 160 ≤ m ≤ 256 was studied in terms of area overhead and throughput improvement. Simple gate area and delay models were used to estimate the throughput of the pipelined and the non-pipe...

Data envelopment analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs). Recently network DEA models been developed to examine the efficiency of DMUs with internal structures. The internal network structures range from a simple two-stage process to a complex system where multiple divisions are linked together with intermediate measures. In general, there ar...

In [Ler53] and [G̊ar56], Leray and Gårding have developed a multiplier technique for deriving a priori estimates for solutions to scalar hyperbolic equations in either the whole space or the torus. In particular, the arguments in [Ler53, G̊ar56] provide with at least one local multiplier and one local energy functional that is controlled along the evolution. The existence of such a local multipli...
