This volume contains the papers and posters selected for presentation at the First European Conference on Smart Sensing and Context (EuroSSC 2006) in Enschede, The Netherlands. EuroSSC 2006 was the ?rst conference of a series aiming at bringing together designers, engineers and researchers to explore two complementary viewpoints: – A device-centric,technology-drivenview: concerning intelligent sensors,s- sor networks and information processing for a new generation of networked devices and environments. – A service-centric, user-driven view: exploring architectures, techniques, and algorithms for context-aware and pro-active applications made possible by thedi?usionofambientcommunication,cooperatingobjects,andinteraction technologies. These subjects are active and relevant research areas in themselves, and there are several conferences that address them separately. EuroSSC 2006, however, considered them both, and especially the symbiosis between them, which we expect to result in very inspiring and interesting discussions, as well as new research ideas on how to combine them. The conference was organized in single tracks covering various issues ra- ing from intelligent sensors, sensor networks, context management and context awareness,andprivacy,toapplicationsandtestbeds. Organizingaconferencefor the ?rst time requires lots of preparations, such as ?nding a publisher, spons- ing organizations,and TPC members and most importantly attracting potential submitters. Fortunately, the amount and quality of the submissions were such that we were in the luxurious position to be able to accept only high quality and relevant papers. The conference attracted world wide attention and submissions came from ?ve continents. A total of 15 accepted full papers and 14accepted posters came from Asia, North America and Europe.

Computationally intensive algorithms for closed loop control and similar systems today can be implemented using reconfigurable FPGA devices. One approach is using soft microprocessor designs and implementing the algorithms as programs. This paper reports about a case study within an ongoing project that investigates a multi-core soft microprocessor solution for a closed-loop control application. Requirements within the project lead to a specialized processor design. Some results from experimental work are presented, demonstrating feasibility and efficiency of the approach.

International Conference on Reconfigurable Computing and FPGAs (ReConFig)

The development of industrial control and measurement systems is often based on modular commercial off the-shelf hardware. Lately, for these platforms reconfigurable I/O modules with field-programmable gate arrays (FPGA) have gained significance, since they allow the implementation of data processing functionality very close to the data acquisition interfaces. However, algorithm complexity and floating-point support are limited by FGPA resources and design methods. This contribution presents an application specific configurable DSP soft core architecture built around a scalable double precision floating-point arithmetic/logic unit. The core can be seamlessly utilized as a functional component in Lab VIEW based FPGA designs. A small case study shows the performance of an example application implemented on the presented core in comparison to other embedded architectures.

A new direction in short-range wireless applications has appeared in the form of high-speed data communication devices for distances of a few meters. Behind these embedded applications, a complex Hardware/Software architecture is built. Dependability is one of the major challenges in these systems. Obviously in such systems, the attribute reliability has to be investigated for various components and at different abstractions levels. This paper presents a hardware platform for wireless system dependability analysis as an alternative for the time consuming global system simulation technique. The platform is built using several instances of one of the commercial FPGA platforms available on the market place. Based on this platform we introduce a new methodology and a flow to investigate the different parts of system dependability at different abstraction levels. The benefits to use the proposed methodology are two fold: first it takes care of the whole system (HW/SW part, mixed RF and wireless part) and second, the hardware platform enables to explore the application's reliability under real environmental conditions in order to study the effect of the environment threats on the system. © 2011 IEEE.

Most of the links in future wireless communication networks will be established over relatively short distances. This new direction in wireless communication is adopted and being developed by embedded multimedia applications leaders. Moreover, these short range communications are introduced into critical applications, where the dependability/reliability is mandatory. Thus, dependability concerns around reliability evaluation becomes an essential question to answer, and poses several challenges. Obviously, it's particularly difficult to investigate the reliability of such mixed HW/SW IPs based systems. Therefore, dependability has to be investigated at different abstractions levels, and for all components integrated into the system being designed. In this paper, we discuss the investigation of dependability in wireless short range systems. Firstly we show how a HW platform based dependability investigation can be a very interactive approach;secondly, we describe a real experience in building a wireless hardware platform for short range systems dependability analysis, and finally, based on this wireless network platform, we propose a dependability flow that takes care of the heterogeneous parts of the wireless embedded systems. © 2012 IEEE.

International Conference on embedded computer systems: architectures, Modeling and Simulation (IC-SAMOS)

作者： Kenneth C. Rovers Marcel D. van de Burgwal Jan Kuper André B. J. Kokkeler Gerard J. M. Smit Computer Architecture for Embedded Systems group CTIT Department of EEMCS University of Twente Enschede Netherlands

Current tools for embedded system design have limited support for modelling the interaction of the system with its physical environment. Furthermore, the natural representation of (streaming, real-time) applications with dataflow models is not supported by most tools. However, integrating multiple domains supports the design of complex interdisciplinary systems and enables model transformations. In this paper we discuss a unified approach, called UniTi, to handle continuous and discrete time models in a single framework, which includes the dataflow model as well. Our approach consists of a transformational design flow, expressed mathematically in a functional language. We formally distinguish the various domains and explain their interaction. In addition, we give guidelines for specifying algorithms such that these transformations can be applied. Our approach is illustrated with a non-trivial case study: beamforming in a phased array system.

International Conference on Communication systems Software and Middleware (COMSWARE)

作者： K. Muthukrishnan N. Meratnia M. Lijding G. Koprinkov P. Havinga Faculty of Computer Science Computer Architecture Design and Test for Embedded Systems group University of Twente Enschede Netherlands

In the last few years, WLAN has seen immense growth and it will continue this trend due to the fact that it provides convenient connectivity as well as high speed links. Furthermore, the infrastructure already exists in most public places and is cheap to extend. These advantages, together with the fact that WLAN covers a large area and is not restricted to line of sight, have led to developing many WLAN localization techniques and applications based on them. In this paper we present a novel calibration-free localization technique using the existing WLAN infrastructure that enables conference participants to determine their location without the need of a centralized system. The evaluation results illustrate the superiority of our technique compared to existing methods. In addition, we present a privacy observant architecture to share location information. We handle both the location of people and the resources in the infrastructure as services, which can be easily discovered and used. An important design issue for us was to avoid tracking people and giving the users control over who they share their location information with and under which conditions

Adaptive resource allocation for streaming applications

International Conference on embedded computer systems: architectures, Modeling and Simulation (IC-SAMOS)

作者： Timon D. ter Braak Hermen A. Toersche André B. J. Kokkeler Gerard J. M. Smit Computer Architecture for Embedded Systems Group Department of Electrical Engineering Mathematics and Computer Science University of Twente Enschede Netherlands

Streaming applications often have latency and throughput requirements due to timing critical signal processing, or the time critical interaction with their environment. Mapping such applications to a multi-core architecture is commonly done at design-time to be able to analyze the complex design-space. However, such design-flows cannot deal with a dynamic platform or a dynamic set of applications. Hardware faults and resources claimed by other applications may render the assumed available resources inaccessible. To avoid the assumptions posed on the state of the platform by a fixed resource allocation, applications should be designed with location transparency in mind. Applications must be analyzed at design-time to determine the required resource budget, independent of which specific resources will be allocated. Sufficient performance can be guaranteed when such applications are mapped onto an architecture in which each resource is arbitrated using a budget scheduler. Within the Cutting edge Reconfigurable ICs for Stream Processing (CRISP) project, a many-core platform is developed that adheres to these requirements. Using the configuration features of the platform, the system is able to control at run-time what resources are being used by the applications. This paper shows that run-time resource allocation can effectively adapt to the available set of resources, providing partial distribution transparency to the user. As an example, a GNSS receiver is mapped to the platform containing faulty hardware components. A few resources remain critical, but in most cases the faulty components can be circumvented, such that adequate resources can be allocated to the application at run-time.

High performance image processing applications area challenging field when targeting embedded processing. Field programmable gate arrays (FPGA) receive a growing interest as implementation platforms, but these solutions have to compete with the state of the art in image processing, which is codefined by graphics processing units (GPU). This paper provides a case study which analyzes the potential of embedded or hybrid implementation on FPGA and GPU for image stack processing in a white light interferometry (WLI) application.

Modern FPGAs (Field Programmable Gate Arrays) are becoming increasingly important when it comes to embedded system development. Within these FPGAs, soft-core processors are often used to solve a wide range of different tasks. Soft-core processors are a cost-effective and time-efficient way to realize embedded systems. The trend for soft-core processors, as well as mainstream CPUs (central processing units), leads to multi-core architectures. Both the necessary memory architectures and the compilers play an important role in this process. In this paper, a novel method that aims at minimizing the necessary memory resources on the FPGA while maximizing the processing speed of any given algorithm is described. In the first step, an application-specializable multi-soft-core processor architecture is presented that is capable of solving problems while adhering to hard real-time deadlines. Its special architecture and other necessary features are discussed. Furthermore, a method for the generation of optimized machine code for each processor core as well as hard real-time compatible deadlock handling mechanisms are presented. Selected algorithms are implemented to demonstrate the functionality and efficiency of the realized approach for different configurations of the multi-soft-core processor architecture.
