Modern DSP systems are often well suited to VLSI implementation. Indeed, they are often technically feasible or economically viable only if implemented using VLSI technologies.. The paper is focused on the design of an efficient VLSI architecture for FIR filters which aims at reducing the power consumption and also to reduce the hardware complexity. In the existing method, design of folded FIR ...

We investigate the fundamental process of sampling using an impulse train, called the shah function [Bracewell], that is skewed in time by a constant offset relative to absolute time 0. We observe that when an originating analog signal is bandlimited, there is little difference between fractionally timeshifting the corresponding sequence, and synchronously sampling the time-shifted analog signa...

Two authors of this paper have shown that by using the frequency-response masking (FRM) technique for designing finite-impulse response (FIR) filters building a two-channel filterbank (FB) with rational sampling factors, the implementation complexity can be reduced compared with the use of direct-form filters for this purpose. In this paper, for designing FBs, a modified version of the FRM tech...

This paper describes a new method for linear phase finite impulse response (FIR) filters design. This new approach, based on the ε-insensitive loss function, allows the design process to take into account not only constraints specified in the frequency domain, but also constraints on the output, time domain, signal. The performances of the proposed approach are shortly illustrated by a high-pas...

This paper presented memory footprint and combinational complexity for two dimensional finite impulse response (FIR) filter to get the systematic design strategy to obtain areadelay-power-efficient architectures. Based on the memory sharing and memory-reuse along with suitable scheduling of computational design of storage architecture the separable and nonseparable filters with less memory foot...

A new family of wavelets is introduced, which is associated with Legendre polynomials. These wavelets, termed spherical harmonic or Legendre wavelets, possess compact support. The method for the wavelet construction is derived from the association of ordinary second order differential equations with multiresolution filters. The low-pass filter associated to Legendre multiresolution analysis is ...

The conventional frequency response masking (FRM) approach is one of the most well-known techniques for the design of sharp transition band finite impulse response (FIR) digital filters. The resulting FRM digital filters permit efficient hardware implementations due to an inherently large number of zero-valued multiplier coefficients. The hardware complexity of these digital filters can further...

The problem of shortening the effective channel impulse response in xDSL is addressed. A new approach is described based on linear phase FIR equaliser filters. The mathematical framework for the LPIRS method is developed and simulation results are presented for several VDSL loops. For a similar performance, the novel method offers a design with considerably lower computational complexity and a ...
