Wavelet transforms have proven to be useful tools for several applications, including signal
analysis, signal compression and numerical analysis. This paper surveys the VLSI …

Asia area prefer Verilog, while US east coast and Europe more frequently use VHDL. For
DSP with FPGAs both languages seem to be well suited, although some VHDL examples …

Several algorithms are reviewed for computing various types of wavelet transforms: the
Mallat algorithm (1989), the'a trous' algorithm, and their generalizations by Shensa. The goal …

A class of VLSI architectures based on linear systolic arrays, for computing the 1-D Discrete
Wavelet Transform (DWT), is presented. The various architectures of this class differ only in …

The recursive pyramid algorithm (RPA) is a reformulation of the classical pyramid algorithm
(PA) for computing the discrete wavelet transform (DWT). The RPA computes the N-point …

This paper presents an iterated short convolution (ISC) algorithm, based on the mixed radix
algorithm and fast convolution algorithm. This ISC-based linear convolution structure is …

This paper presents a novel approach for implementing area-efficient parallel (block) finite
impulse response (FIR) filters that require less hardware than traditional block FIR filter …

Based on fast finite-impulse response (FIR) algorithms (FFAs), this paper proposes new
parallel FIR filter structures, which are beneficial to symmetric coefficients in terms of the …

Hardware implementations represent the major challenges when digital signal processors
for ultra-wideband (UWB) signals must be developed. Due to the limitation of the maximum …

Parallel (or block) FIR digital filters can be used either for high-speed or low-power (with
reduced supply voltage) applications. Traditional parallel filter implementations cause linear …
