Investigating
Power Reduction for NoC-Based Spiking Neural Network Platforms using Channel
Encoding
Neil

Magee Campus, Northern Ireland, UK), Snaider Carrillo (School of Computing and
Intelligent Systems, University of Ulster, Magee Campus, Northern Ireland, UK),
Jim Harkin (School of Computing and Intelligent Systems, University of Ulster,
Magee Campus, Northern Ireland, UK) and Liam McDaid (School of Computing and
Intelligent Systems, University of Ulster, Magee Campus, Northern Ireland, UK)
Recent
focus has been placed on exploring the possibility to switch from parallel to
serial data links between NoC routers in order to improve signal integrity in
the communication channel. However, moving streams of data between the parallel
path of the internal router and external serial-channel links between them
consumes additional power. One challenge is encoding the data and minimise the
switching activity of data in the serial links in order to reduce the
additional power dissipation; while under real-time and minimal hardware
constraints. Consequently, proposed is a novel low area/power decision circuit
for NoC channel encoding which identifies in real-time packets for encoding and
extends the existing SILENT encoders/decoders to further minimise power
consumption and demonstrates the power performance savings of the decision
circuit and modified (en)decoders using example test traffic with the EMBRACE
NoC router, a mixed signal spiking neural network (SNNs) embedded platform.

TWO
Compensating
Resource Fluctuations by Means of Evolvable Hardware: The Run-Time
Reconfigurable Functional Unit Row Classifier Architecture

Paderborn, Paderborn, Germany) and Jim Torresen (University of Oslo, Norway)
The
evolvable hardware (EHW) paradigm facilitates the construction of autonomous
systems that can adapt to environmental changes and degradation of the
computational resources. Extending the EHW principle to architectural
adaptation, the authors study the capability of evolvable hardware classifiers
to adapt to intentional run-time fluctuations in the available resources, i.e.,
chip area, in this work. To that end, the authors leverage the Functional Unit
Row (FUR) architecture, a coarse-grained reconfigurable classifier, and apply
it to two medical benchmarks, the Pima and Thyroid data sets from the UCI
Machine Learning Repository. While quick recovery from architectural changes
was already demonstrated for the FUR architecture, the authors also introduce
two reconfiguration schemes helping to reduce the magnitude of degradation
after architectural reconfiguration.

PAPER
THREE
Automatic Machine Code Generation for a Transport Triggered Architecture
using Cartesian Genetic Programming
James Alfred Walker (Department of Electronics, University of York, York,
UK), Yang Liu (Department of Electronics, University of York, York, UK),
Gianluca Tempesti (Department of Electronics, University of York, York, UK),
Jon Timmis (Departments of Electronics and Computer Science, University of
York, York, UK) and Andy M. Tyrrell (Department of Electronics, University of
York, York, UK)
Transport
triggered architectures are used for implementing bio-inspired systems due to
their simplicity, modularity and fault-tolerance. However, producing efficient,
optimised machine code for such architectures is extremely difficult, since
computational complexity has moved from the hardware-level to the
software-level. Presented is the application of Cartesian Genetic Programming
(CGP) to the evolution of machine code for a simple implementation of transport
triggered architecture. The effectiveness of the algorithm is demonstrated by
evolving machine code for a 4-bit multiplier with three different levels of
parallelism. The results show that 100% successful solutions were found by CGP
and by further optimising the size of the solutions, it’s possible to find
efficient implementations of the 4-bit multiplier. Further analysis of the
solutions showed that use of loops within the CGP function set could be
beneficial and was demonstrated by repeating the earlier 4-bit multiplier
experiment with the addition of a loop function.

PAPER
FOUR
Multi-View Human Body Pose Estimation with CUDA-PSO
Luca Mussi (Henesis s.r.l., Parma, Italy), Spela Ivekovic (Department of
Mechanical & Aerospace Engineering, University of Strathclyde, Glasgow,
UK), Youssef S.G. Nashed (Department of Information Engineering, University of
Parma, Parma, Italy) and Stefano Cagnoni (Department of Information Engineering,
University of Parma, Parma, Italy)
The
authors formulate the body pose estimation as a multi-dimensional nonlinear
optimization problem, suitable to be approximately solved by a meta-heuristic,
specifically, the particle swarm optimization (PSO). Starting from multi-view
video sequences acquired in a studio environment, a full skeletal configuration
of the human body is retrieved. They use a generic subdivision-surface body
model in 3-D to generate solutions for the optimization problem. PSO then looks
for the best match between the silhouettes generated by the projection of the
model in a candidate pose and the silhouettes extracted from the original video
sequence. The optimization method, in this case PSO, is run in parallel on the
Graphics Processing Unit (GPU) and is implemented in Cuda-C™ on the nVidia
CUDA™ architecture. The authors compare the results obtained by different
configurations of the camera setup, fitness function, and PSO neighborhood
topologies.

CALL
FOR PAPERS
The International Journal of Adaptive, Resilient and Autonomic
Systems (IJARAS) examines systems and organizations characterized by the
following two properties: the ability to self-adapt to the characteristics
of rapidly changing and turbulent environments by adopting complex
individual and social strategies and the ability to control their
changes to prevent the invalidation of their original mission statements.
The central focus of IJARAS is on modeling, simulating, designing,
developing, maintaining, evaluating, and benchmarking such “entelechial
systems”. Perception, awareness, and the planning and execution of
resilient adaptation behaviors in systems and organizations are central topics of
the journal. Such systems range from individual and simple embedded systems
with limited perception and predefined specialized behaviors to complex
hybrid social organizations like cyber-physical societies or
service-oriented communities, whose emerging behaviors are many and, in
some cases, difficult to predict. IJARAS focuses on the full spectrum of
these problems providing academicians, practitioners, and researchers with
awareness and insight on conceptual models, applied and theoretical approaches,
paradigms, and other technological innovations on self-adaptive and/or
self-resilient systems and organizations of any scale and nature.
Mission
Society is currently
experiencing the increasing population of “things,” able to autonomously
link with each other and enact complex strategies to achieve tasks.
The emergence of the Semantic Web, the Internet-of-Things, Ambient
Intelligence, and cyber-physical societies make it impossible to capture the
intricacies of the future highly dynamic and turbulent networks of
interrelated computer-based and hybrid components. As such, it is
important that systems are designed to self-adapt to changes without
diverging from their intended functions as prescribed in their
specifications. The mission of the International Journal of Adaptive,
Resilient and Autonomic Systems (IJARAS) is to offer awareness and
visibility to novel techniques and methods to achieve self-adaptability
and self-resilience when systems and organizations are deployed in environments
where change is the rule rather than the exception. IJARAS is also a tool
to enhance the awareness of the key role played by said techniques and
methods: engineering self-adaptive and self-resilient systems and organizations
is an urgent necessity to keep society resilient in the face of the
technology that sustains it. The journal pursues its mission by
addressing researchers, practitioners, engineers, educators, and
professionals and by publishing novel results on each of the diverse
components of such a complex and multi-disciplinary research problem.
