This work deals with the problem of designing an optimal structure of a public service system. The problem can be often formulated as a weighted p-median problem. Real instances of the problem are characterized by big numbers of possible service center locations, which can take the value of several hundreds or thousands. The optimal solution can be obtained by the universal IP solvers only for ...

In this paper, we propose an MSD (most significant digit) multiplier based on an MSB (most significant bit) multiplier over GF(2). The proposed multiplier is based on connecting D (digit size)-bit bit-operations in series. In each digit operation in our proposed multiplier, the “left shift and reduction operation” is serially performed for each of D bits. Because registers for storing intermedi...

In this paper, a low-complexity Programmable Cellular Automata (PCA) based versatile modular multiplier in GF(2) is presented. The proposed versatile multiplier increases flexibility in using the same multiplier in different security environments, and it reduces the user's cost. Moreover, the multiplier can be easily extended to high order of m for more security, and low-cost serial implementat...

A low latency digit serial multiplier for GF(2m) that can be pipelined to the bit-level is presented in this paper. Unlike existing structures, the new multiplier does not put any restriction on the type of generator polynomial used or the digit size. Furthermore, the latency of the new multiplier is significantly less than the latency of the existing bit-level pipelined digit-serial multiplier...

assess the ecological effects of economic activity on the water, earth and man in the iranian economy approach using input - output tablewater is a vital resource for each biological and economic phenomenon. water is considered as a production input. production is not possible without water in all economic sectors. also, the environment including air, soil, fauna and plants utilize water in the...

A hybrid radix-4/radix-8 architecture targeted for high bit, general purpose, digital multipliers is presented as a compromise between the high speed of a radix-4 multiplier architecture and the low power dissipation of a radix-8 multiplier architecture. In this hybrid radix4/radix-8 multiplier architecture, the performance bottleneck of a radix-8 multiplier, the generation of three times the m...

This paper presents the design redundant Binary multiplier for 32*32bit number multiplication. Modern computer system is a dedicated and very high speed unique multiplier. Therefore, this paper presents the design a Redundant Binary multiplier. The proposed system generates M, N and interconnected blocks. By extending bit of the operands and generating an additional product the proposed system ...

This paper analyzes the power consumption of an array pipelined multiplier. To precisely realize a low power pipelined multiplier, the analytical model for a clocking system is presented. Simulation results show that the storage element is the key-component in a high performance pipelined multiplier macro. Compared with the conventional DFF and latch, the new low power DFF as PTTFF [6] achieves...

In this Paper, Urdhva tiryakbhyam Sutra is first applied to the binary number system and is used to develop digital multiplier architecture. This is shown to be very similar to the popular array multiplier architecture. This Sutra also shows the effectiveness of to reduce the NXN multiplier structure into an efficient 4X4 multiplier structures. Nikhilam Sutra is then discussed and is shown to b...
