Multiplier is an important key element used for arithmetic operations in digital signal processor. Power consumption in multiplier is more when compared with adders and subtractors. So reducing the power consumption of multiplier makes a digital signal processor more efficient. A Wallace tree multiplier is an efficient high speed multiplier that multiplies two integers. Here a 4*4 Wallace tree ...

High-speed parallel multipliers are one of the keys in RISCs (Reduced Instruction Set Computers), DSPs (Digital Signal Processors), and graphics accelerators and so on. Array multiplier, Booth Multiplier and Wallace Tree multipliers are some of the standard approaches used in implementation of binary multiplier which are suitable for VLSI implementation. A simple digital multiplier (henceforth ...

There are different CMOS multiplier circuits are analyzed names as Braun multiplier, Wallace tree multiplier, Row bypass Braun multiplier, Column bypass Braun multiplier, Row and Column bypass Braun multiplier and these mu...

The purpose of this work is to study mortar methods for linear elasticity using standard low order finite element spaces. Based on residual stabilization, we introduce a stabilized method and compare it the unstabilized mixed method. For simplicity, both use Lagrange multiplier defined trace mesh inherited from one side interface only. We derive quasi-optimality estimate present stability crite...

The Wallace Multiplier is mainly used in the Arithmetic & Logic Unit (ALU) to perform the scientific computation in processors, controller etc... The existing multiplication technique like booth multiplier, array multiplier etc requires more time in multiplications. Hence Wallace Multiplier has been designed by using the parallel process to reduce the delay. The regular Wallace Multiplier requi...

This paper uses the Popov-Tsypkin multiplier (which has intimate connections to mixed structured singular value theory) to design robust H∞ estimators for uncertain, linear discrete-time systems and considers the application of robust H∞ estimators to robust fault detection. The key to estimator-based, robust fault detection is to generate residuals which are robust against plant uncertainties ...

In this paper a low power and low area array multiplier with carry save adder is proposed. The proposed adder eliminates the final addition stage of the multiplier than the conventional parallel array multiplier. The conventional and proposed multiplier both are synthesized with 16-T full adder. Among Transmission Gate, Transmission Function Adder, 14-T, 16-T full adder shows energy efficiency....

This paper considers the design of robust`1 estimators based on multiplier theory (which is intimately related to the mixed structured singular value theory) and the application of robust`1 estimators to robust fault detection. The key to estimator-based, robust fault detection is to generate residuals which are robust against plant uncertainties and external disturbance inputs, which in turn r...

The key to estimator-based, robust fault detection is to generate residuals which are robust against plant uncertainties and external disturbance inputs, which in turn requires the design of robust estimators. Hence, this paper considers the design of robust H 2 estimators using a parameter-dependent bounding function approach in conjunction with multiplier theory (which is intimately related t...

Processor speed largely governed by the multiplier architectures. It is desired to have faster ALU with lower power consumption for portable applications to have good battery life. Hence, there is need to address different multiplier architectures. In this paper, the analysis of 4-bit multiplier using a Vedic Mathematics (Urdhva Tiryagbhyam sutra) and conventional multiplier with two different ...
