Article
Full-text available
In recent years, systems that monitor and control home environments, based on non-vocal and non-manual interfaces, have been introduced to improve the quality of life of people with mobility difficulties. In this work, we present the reconfigurable implementation and optimization of such a novel system that utilizes a recurrent neural network (RNN)...
Article
Full-text available
In an era of complex networked parallel heterogeneous systems, simulating independently only parts, components or attributes of a system-under-design is a cumbersome, inaccurate and inefficient approach. Moreover, by considering each part of a system in an isolated manner, and due to the numerous and highly complicated interactions between the diff...
Article
This paper introduces a novel electroencephalogram (EEG) data classification scheme together with its implementation in hardware using an innovative approach. The proposed scheme integrates into a single, end-to-end trainable model a spatial filtering technique and a neural network based classifier. The spatial filters, as well as, the coefficients...
Article
The growing use of hardware accelerators in both embedded (e.g. automotive) and high-end systems (e.g. Cloud infrastructure) triggers an urgent demand for simulation frameworks that can simulate in an integrated manner all the components (i.e. CPUs, Memories, Networks, Hardware Accelerators) of a system-under-design(SuD). By utilizing such a simula...
Conference Paper
Full-text available
In an era of complex networked heterogeneous systems, simulating independently only parts, components or attributes of a system under design is not a viable, accurate or efficient option. The interactions are too many and too complicated to produce meaningful results and the optimization opportunities are severely limited when considering each part...
Conference Paper
Full-text available
In this demo, we present COSSIM, an open-source simulation framework for cloud applications. Our solution models the client and server computing devices as well as the network that comprise the overall system and thus provides cycle accurate results, realistic communications and power/energy consumption estimates based on the actual dynamic usage s...
Article
Every HPC system consists of numerous processing nodes interconnect using a number of different interprocess communication protocols such as Messaging Passing Interface (MPI) and Global Arrays (GA). Traditionally, research has focused on optimizing these protocols and identifying the most suitable ones for each system and/or application. Recently,...
