Improvements in semiconductor integration density and the resulting problem of having to manage designs of increasing complexity is an old one, but still current. The new challenge lies in a new level of architecture heterogeneity, e.g. mixing hard-wired digital circuits with software programmed signal processors on one die. Hence, we are moving by one level of abstraction from semi-custom stan...

Fast advances in several signal processing techniques, along with cost-effective digital technologies for their implementation, are ready to address important manufacturing and machine monitoring issues for which no solution currently exists. Among new technologies are advances in wavelet and time-frequency signal analysis. By virtue of their ability to characterize both transient phenomena and...

− An appropriate choice of the computing devices employed in digital signal processing applications requires to characterize and to compare various technologies, so that the best component in terms of cost and performance can be used in a given system design. In this paper, a benchmark strategy is presented to measure the performances of various types of digital signal processing devices. Altho...

This paper presents the design and implementation of three System on Chip (SoC) cores, which implement the Digital Signal Processing (DSP) functions: Finite Impulse Response (FIR) filter, Infinite Impulse Response (IIR) filter and Fast Fourier Transform (FFT). The FIR filter core is based on the symmetrical realization form, the IIR filter core is based on the Second Order Sections (SOS) archit...

In this note it is only possible to give a short description of affine wavelet theory and to indicate some reasons, why wavelet theory has attracted so much attention from the applied community recently. Besides a description of the basic ideas this note provides a guide to the relevant literature (published or presently submitted for publication) and some recent developments which are of inter...

Stabilization of the particle beam position with respect to the focusing optics in the third generation synchrotron light sources is crucial to achieving low emittance and high brightness. For this purpose, global and local beam orbit correction feedbacks will be implemented in the APS storage ring. In this article, we will discuss application of digital signal processing to par-ticle/photon be...

This paper presents an approach to the wordlength allocation and optimization problem for linear digital signal processing systems implemented as custom parallel processing units. Two techniques are proposed, one which guarantees an optimum set of wordlengths for each internal variable, and one which is a heuristic approach. Both techniques allow the user to tradeoff implementation area for ari...

In general the ultrasonic testing is used for flaw detection and localization in tested materials. Flaws in materials are commonly characterized in measured ultrasonic signals by faults echoes. Ultrasonic signals measured on materials with coarse grained structure contain relative high level of noise. This undesirable part of ultrasonic signal should be reduced to make the fault echo detection ...

The area of signal processing is very wide. In this review paper we will focus on how the theory of nonnegative matrices may arise in the field of digital filter design: an area in which the role of nonnegative matrices is increasingly relevant due to the development of new technologies in the field of optical components and charge coupling devices. r 2005 Elsevier B.V.
