An alternative superscalar architecture with integer execution units only

引用

5th International Workshop on Advanced Parallel Processing Technologies, APPT 2003

作者： Lee, Kenneth K. C. Grosspietsch, K.-E. Chan, Y.K. Department of Computer Science City University of Hong Kong Hong Kong Fraunhofer-Gesellschaft Institute of Autonomous Intelligent Systems Sankt Augustin Germany

ISBN: (纸本)3540200541

Superscalar architecture resulting in aggressive performance is a proven architecture for general purpose computation. The negative side effect of aggressive performance is the need for higher number of register read/write ports to supply operands to multiple execution units;the need to resolve false data dependence and true data dependence;the need to dispatch operand ready instructions to execution units and finally retire out of order executed instructions to program order. A processor architecture is proposed in here to address at least some of the above negative side effects. This processor architecture is call LITERAL QUEUE ARCHITECTURE(LQA). In here, LITERAL has the meaning of immediate data. In LQA, opcode and operands in an instruction are treated as a self contained structured element and forms the necessary and sufficient condition for instruction execution. Sequence of instructions embedded with LITERALS are treated as elements in a QUEUE. The elements are executed with respect to time and rotated out of the QUEUE while new elements are rotated into the QUEUE. © Springer-Verlag Berlin Heidelberg 2003.

引用

International Congress Series 2003年第C期1256卷 1133-1138页

作者： Bourantas, C. Fotiadis, D.I. Kourtis, I.C. Michalis, L.K. Plissiti, M. Department of Cardiology Medical School University of Ioannina GR 45110 Ioannina Greece Department of Computer Science Unit of Medical Technology and Intelligent Information Systems University of Ioannina GR 45110 Ioannina Greece Biomedical Research Institute-FORTH GR 45110 Ioannina Greece Michailideion Cardiology Center GR 45110 Ioannina Greece

We have developed an efficient method for 3D reconstruction of coronary arteries. Our approach is based on the fusion of intravascular ultrasound (IVUS) and biplane angiography. The method includes an efficient algorithm for the automatic identification of the regions of interest in IVUS images and a novel methodology for the extraction of the catheter path from biplane angiographies. The estimation of IVUS frames relative twist and the computation of first IVUS frame absolute orientation is also investigated. To assess the performance of the method, a validation procedure is introduced. Several metrics are obtained to verify the reliability of our method in the description of coronary artery morphology. © 2003, Elsevier B.V. All rights reserved.

IEEE EMBS International Conference on Information Technology Applications in Biomedicine (ITAB)

作者： K.M. Kontaxis G.C. Sakellaris D.I. Fotiadis Unit of Medical Technology and Intelligent Information Systems Department of Computer Science University of Ioannina and Biomedical Research Institute FORTH Ioannina Greece

In this paper we describe an innovative system that aims to integrate heterogeneous distributed healthcare information resources. It is based on the advantages of technologies like the extensible markup language (XML), controlled vocabularies (CVs) such as wordnet and the unified medical language system (UMLS), as well as the common object request broker architecture (CORBA). The proposed approach is based on three key functionalities: a) the user-transparent acquisition of each source's structural information, b) the lexical and semantical analysis based elaboration of the user's initial query and c) the appropriate combination of the results from the two previous functionalities, aiming to the selection of the query that corresponds with each source. CORBA is responsible for providing the interoperability between objects in this disparate distributed environment.

作者： F. Vartziotis D.I. Fotiadis I.E. Lagaris A. Likas Unit of Medical Technology and Intelligent Information Systems Department of Computer Science University of Ioannina (UoI) Ioannina Greece Department of Computer Science University of Ioannina and Biomedical Research Institute FORTH Ioannina Greece

In this article, we present PLACEBO, an innovative software and hardware platform, which intends to solve biomedical problems formulated in terms of partial differential equations. It can be networked with various imaging devices, such as MRI and CT and can be used for pre-operative surgical planning. It employs an effective computational environment for solving partial differential equations, which is based on neural networks. This approach, in order to exploit the parallel character of the neural networks, is implemented partly in specialized hardware hosted on a commercial PC. There are two operation levels. A user-level, targeting health professionals that need to solve a set of predefined biomedical problems, and a bioengineering level, which allows the construction of problem sets. Since ease of use is of paramount importance for these kind of platforms, a friendly graphical user-interface is being developed.

Buffering fuzzy maps in GIS

引用

Spatial Cognition and Computation 2003年第2-3期3卷 207-222页

作者： Guesgen, Hans W. Hertzberg, Joachim Lobb, Richard Mantler, Andrea Department of Computer Science University of Auckland PMB 92019 Auckland New Zealand Fraunhofer Institute for Autonomous Intelligent Systems Germany University of North Carolina United States

In this paper, we show how standard GIS operations like the complement, union, intersection, and buffering of maps can be made more flexible by using fuzzy set theory. In particular, we present a variety of algorithms for operations on fuzzy raster maps, focusing on buffer operations for such maps. Furthermore, we show how widely-available special-purpose hardware (in particular, z-buffering in graphics hardware) can be used for supporting buffer operations in fuzzy geographic information systems (GIS). © 2003, Lawrence Erlbaum Associates, Inc.
