Turbo NOC: a framework for the design of Network-on-Chip-basedturbo decoder architectures
Full text linkThis paper proposes a general framework for the design and simulation of network-on-chip-based turbo decoder architectures. Several parameters in the design space are investigated, namely, network topology, parallelism degree, the rate at which messages are sent by processing nodes over the network, and routing strategy. The main results of this analysis are as follows: 1) the most suited topologies to achieve high throughput with a limited complexity overhead are generalized de Bruijn and generalized Kautz topologies and 2) depending on the throughput requirements, different parallelism degrees, message injection rates, and routing algorithms can be used to minimize the network area overhead
VLSI implementation of a multi-mode turbo/LDPC decoder architecture
Full text linkFlexible and reconfigurable architectures have gained wide popularity in the communications field. In particular, reconfigurable architectures for the physical layer are an attractive solution not only to switch among different coding modes but also to achieve interoperability. This work concentrates on the design of a reconfigurable architecture for both turbo and LDPC codes decoding. The novel contributions of this paper are: i) tackling the reconfiguration issue introducing a formal and systematic treatment that, to the best of our knowledge, was not previously addressed; ii) proposing a reconfigurable NoCbased turbo/LDPC decoder architecture and showing that wide flexibility can be achieved with a small complexity overhead. Obtained results show that dynamic switching between most of considered communication standards is possible without pausing the decoding activity. Moreover, post-layout results show that tailoring the proposed architecture to the WiMAX standard leads to an area occupation of 2.75 mm2 and a power consumption of 101.5 mW in the worst case
Renewable Energies to Promote Local Development
No full textThis book is intended as a contribution towards a more inclusive sustainable future. It conceptualizes energy as a central element of development and renewable as a key condition for sustainable development. By describing the technical, economic and policy conditions that are necessary for the successful deployment of renewable energy, it provides recommendations for unleashing, in developing regions, a sustainable development based on more equitable distribution of resources. The need to provide universal energy access to reduce poverty while preserving the environment and limiting climate change requires a new paradigm in the way energy is produced, distributed and used. Decentralized renewable energy systems based on sound technical solutions, solid business models and enabling policies, need to be deployed. Energy is needed to satisfy basic living needs and to give access to public services that are relevant to human and social development. Energy also represents also an income opportunity for people as it enables new
productive activities and thus triggers socio-economic development. Distributed renewable energy can and should become the first option for achieving universal energy access since it has proven to be in several cases the most cost-effective and affordable option.
Energy is a cross cutting enabler that should be integrated into wider social, economic and environmental policies. From this perspective, the book provides a comprehensive multi objective and multi criteria analysis that goes beyond the often shortsighted and simplistic financial analysis, with the aim to represent a step towards the achievement of innovative solutions. A wide panorama of the contribution of renewable energy to sustainable development is presented in four of the five parts of the book, that readers might read separately, as each one stands on its own and tells a distinctive part of the story. The fifth part gives space to specific experiences coming from different
stakeholders quite active in the field of access to energy. The book brings together several authors from different parts of the world and
professional backgrounds ranging from private sector to academia, international organizations, NGOs and governments to give a comprehensive view of the role of renewable energy in ensuring sustainable development. It is also builts on the long experience of the three editors in education and in the promotion and implementation of renewable energy projects in developing countries
