5. 4. Utilizing Heterogeneity in Manycore Architectures for Streaming Applications

   Författare :Süleyman Savas; Tomas Nordström; Zain Ul-Abdin; Håkan Grahn; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manycores; parallel architectures; parallelism; streaming applications; dataflow; manycore design; heterogeneous manycores;

   Sammanfattning : In the last decade, we have seen a transition from single-core to manycore in computer architectures due to performance requirements and limitations in power consumption and heat dissipation. The first manycores had homogeneous architectures consisting of a few identical cores. LÄS MER

7. 5. Theoretical simulations of environment-sensitive dynamical systems for advanced reservoir computing applications

   Författare :Vasileios Athanasiou; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environment-sensitive memristor; organic electrochemical transistor; Sensing; constant phase element; neuromorphic computations; memristor networks; memristor;

   Sammanfattning : The possibility of building intelligent sensing substrates that both collect information about an environment and analyze it in real-time has been investigated theoretically. In a typical setup, a dynamical system is assumed to interact with the environment over time. The system operates as a reservoir computer acting as a reservoir of states. LÄS MER
