In the explosive growth of wireless and networking applications, Digital Signal Processing (DSP) operations are extensively used for characterizing and controlling the discrete input signals. For those DSP operations, Finite Impulse Response (FIR) filter is used to filter the unwanted/noise/distorted signals from the discrete input signals. In this study, design of Pipelined Distributed Arithme...

The need for both speed and increased precision in modern digital signal processing (DSP) applications represents a serious implementation obstacle. This paper explores the arithmetic benefits provided by the residue number system (RNS) for the design of such systems. Concretely, the fusion of the RNS with the popular distributed arithmetic (DA) is considered for the implementation of a discret...

In present work forced convection flow in a channel partly filled with a porous media under asymmetric heat flux boundary condition has been investigated. The porous material is distributed on the one wall. Darcy–Brinkman and LTNE model have been assumed in order to solve momentum and energy equations, respectively. Fully developed conditions are considered in order to solve velocity and the te...

In this paper a Split Radix FFT without the use of multiplier is designed. All the complex multiplications are done by using Distributed Arithmetic (DA) technique. For faster calculation parallel prefix adder is used. Basically high radix algorithms are developed for efficient calculation of FFT. These algorithms reduces overall arithmetic operations in FFT, but increases the number of operatio...

Currently there are design barriers inhibiting the implementation of high-precision digital signal processing (DSP) objects with field programmable logic (FPL) devices. This paper explores overcoming these barriers by fusing together the popular distributed arithmetic (DA) method with the residue number system (RNS) for use in FPL-centric designs. The new design paradigm is studied in the conte...

This paper presents an efficient implementation of Finite Impulse Response Filter (FIR) using Distributed Arithmetic (DA) architecture. Here, the multipliers in FIR filter are replaced with multiplierless DA based technique. The DA based technique consists of Look Up Table (LUT), shift registers and scaling accumulator. Analysis on the performance of various filter orders with various partition...

A real time correlator design based on the principles of Distributed Arithmetic (DA) is described. This design is shown to be more efficient in terms of memory requirement than the direct DA implementation, specially when the number of coefficients is large. Since, the proposed architecture implements the sum of product evaluation, it can be easily extended to finite and infinite response filte...

Distributed arithmetic (DA)-based computation is well known for efficient memory-based implementation of Finite impulse response (FIR) filter where the filter outputs are computed as inner-product of input-sample vectors and filter-coefficient vector. In this paper, we show that the LUT multiplier based approach in which the memory elements store all the possible values of product of filter co-...
