Abstract: The establishment of optical fiber as the dominant mean of data transfer a few decades ago, vastly changed the telecom world and lead to the Internet era that we experience today. The evolution path of optical communications never stopped since its introduction and even now it faces great challenges and experiences drastic changes. So, what are the driving forces of the evolution of optical communications today? We discuss the current status of optical communication technology and highlight the reasons for its continuous evolution. We identify key domains that researchers are now focusing their efforts and also discuss the role of photonic integration in the commercialization of optical technology. Finally, the introduction of optical communication technologies to datacom is discussed.

Abstract: The rapidly-growing capacity of Field Programmable Gate Arrays (FPGAs), combined with the steady introduction of hardwired support for a multitude of diverse interfaces and functionalities, has promoted FPGAs to an attractive and capable platform for hosting even extended System-on-Chip (SoC) designs. The integration of the ovelaid (on-FPGA or soft) platform and the communication of its components requires also an efficient overlaid communication mechanism. Scalable interconnection networks that use a network of switches connected with point-to-point links can parallelize the communication between soft modules and improve performance significantly. Such on-chip interconnection networks are already a mainstream technology for ASICs, while they are becoming a need and critical in FPGA-based systems. ASIC-oriented interconnection networks even if appropriately customized for the on-chip environment, still lead to sub-optimal designs when transferred directly to FPGAs. This deficit is attributed to the inefficient mapping of the network’s switches and their components to the configurable logic array of the FPGA, which is a peculiar hardware realization substrate in terms of the relative speed and cost of logic vs. wires vs. memory. This talks presents the implementation constraints set by the FPGA fabric for the design of soft interconnection networks and presents new FPGA-targeted architectures. The described techniques focus on the fined-grained decomposition of the switch and the adoption of an elastic flow control mechanism.

Biography: Georgios Dimitrakopoulos received the Diploma in Computer Engineering from the Computer Engineering and Informatics Dept. of the University of Patras in 2001. In 2003 he completed the M.Sc. in “Integrated Hardware- Software Systems” and in 2007 he earned the PhD from the same department. Between 2008 and 2010 he worked as a Postdoctoral fellow at the Computer architecture and VLSI Systems Lab of the Institute of Computer Science (ICS) of the Foundation for Research and Technology Hellas (FORTH) and at the University of Crete. Later on, he was appointed as a Lecturer to the Informatics and Communication Engineering Department, of the University of West Macedonia, Kozani, Greece. Since January 2012, he is a Lecturer of Digital Integrated Circuits in the Electrical and Computer Engineering Department of the Democritus University of Thrace (DUTH), Xanthi, Greece.
G. Dimitrakopoulos has served as a program-cochair of INA-OCMC 2012-2013 workshops co-located with HIPEAC conference. He also served on the technical program committee FPL (2011, 2012), DATE (2011,2013), and ICECS 2011, conferences, as well as INAOCMC (2010-2011), NoCArch (2008-2012), UCHPC 2012 and UMHI 2012 workshops.

Seminar: Grid-Connected Small Wind Electric Systems and the Bidirectional Impact between distributed RES and Small Island Grids

by Jake T.

Andreas Armenakis

Venue: Unesco Amphitheatre, University of Nicosia

Wednesday, June 20, 2012, 6-7 pm


The ambitious European 20-20-20 targets will increase the penetration of Renewable Energy Sources (RES) in the grid, including small and efficient units distributed in the medium or low voltage networks. As Distributed Generation (DG) spread in a geographic area, time, location and weather inter-dependencies, loads and demands get more importance, introducing breakthrough changes in the way electricity will be generated, distributed and used. Due to the increase in the numbers of RES connected to the Distribution Network, and the requirement of the European Distribution System Operators (EDSO) to integrate them sufficiently into the network, grid code compliance rules have been implemented to ensure system contribution of RES without disturbing the quality, safety, and reliability of the grid. Before connection to the grid, RES must verify that they comply with regulations, such as voltage control – both steady state and dynamic, voltage dependent reactive power injection or absorption, and fault ride through stability.


Andreas Armenakis graduated in Electrical Engineering (Leipzig) followed by a Master in Engineering (Berlin). He worked for 10 years in Germany for Siemens and Preussag (today Babcock) and also in Cyprus for the Carlsberg Brewery, designing and executing complex Energy and Automation projects. Today, Andreas works for the Electricity Authority of Cyprus, developing the High Voltage Distribution Network, including the integration of Renewable Energy Sources (RES). His publications are mostly related to Energy Management and Integration of RES.

Light refreshments will be provided.
