title = "Low power architectures for digital signal processing",
abstract = "Low power architectures for digital signal processing algorithms requiring inner product computation are presented. In the first step a power efficient memory organization exploiting data reuse is determined. In the second step an order of evaluation of the partial products that reduces the switching activity at the inputs of the computational units is derived. Information related to both coefficients which are static and data which are dynamic, is used to drive the reordering of computation. Experimental results for several signal processing algorithms prove that the proposed techniques lead to significant savings in net switching activity and thus in power consumption.",

note = "Funding Information: Dr. Thanos Stouraitis is a Professor of Electrical and Computer Engineering at the University of Patras, Greece. He has also served on the faculty of The Ohio State University and the University of Florida. He received his Ph.D. in Electrical Engineering from the University of Florida in 1986 (for which he received the Outstanding Ph.D. Dissertation Award), an MSc. in Electrical & Computer Engineering from the University of Cincinnati in 1983, an MS in Electronic Automation from the University of Athens, Greece, in 1981, and a BS in Physics from the University of Athens, Greece, in 1979. His current research interests include signal and image processing, application-specific processor technology and design, design and architecture of optimal digital systems, and computer arithmetic. He leads several DSP processor design projects funded by the European Union and the Greek Government. He has served as Technical Manager of The Athena Group, 1986–1987, and a researcher of the National Electrical Manufacturers Association (NEMA) Laboratories, Cincinnati, Ohio, 1982–1983. He has authored and co-authored over 70 papers. He holds one patent on DSP processor design. He has authored several book chapters, the Univ. of Patras Press book “Digital Signal Processing,” and co-authored the Marcel Dekker book “Digital Filter Design Software for the IBM PC”. He serves as an Editor-at-Large for Marcel Dekker and as a consultant for various industries. He regularly reviews for the IEEE SP, C&S, C, and Education Transactions, for IEE Proceedings E, F, G, and for conferences like IEEE ICASSP, ISCAS, VLSI 9*, Computer Arithmetic, Euro DAC, etc. He also reviews proposals for NSF, the European Commission, and other agencies. He is the President Elect of the VLSI Systems and Applications (VSA) Technical Committee of the IEEE Circuits and Systems Society and a member of the DSP Technical Committee of the IEEE Signal Processing Society. He was the General Chair of the 1996 IEEE Int. Conf. on Electronis, Circuits, and Systems (ICECS). He has served as Chair or as a member of the Technical Program Committees of various IEEE Conferences. ",
