This paper presents an Immersive Telepresence system for Entertainment and Meetings (ITEM). The system aims to provide a radically new video communication experience by seamlessly merging participants into the same virtual space to allow a natural interaction among them and shared collaborative contents. With the goal to make a scalable, flexible system for various business solutions as well as...

The vision of connecting billions of battery operated devices to be used for diverse emerging applications calls for a wireless communication system that can support stringent reliability and latency requirements. Both reliability and energy efficiency are critical for many of these applications that involve communication with short packets which undermine the coding gain achievable from large ...

Abstract: Nowadays wireless sensor netwoks (WSN) technology, wireless communications and digital electronics have made it realistic to produce a large scale miniaturized devices integrating sensing, processing and communication capabilities. The focus of this paper is to present an innovative mobile platform for heterogeneous sensor networks, combined with adaptive methods to optimize the commu...

The polyhedral model provides powerful abstractions to optimize loop nests with regular accesses. Affine transformations in this model capture a complex sequence of execution-reordering loop transformations that can improve performance by parallelization as well as locality enhancement. Although a significant body of research has addressed affine scheduling and partitioning, the problem of auto...

A long running program often spends most of its time in nested loops. The polyhedral model provides powerful abstractions to optimize loop nests with regular accesses for parallel execution. Affine transformations in this model capture a complex sequence of execution-reordering loop transformations that improve performance by parallelization as well as better locality. Although a significant am...

Mainstream electronic designs are realized by Systems-on-Chips (SoCs) that push the limits of integration. The advancement of manufacturing technologies in terms of integration leads us to SoCs with many (e.g., 10–1000) digital units (e.g., processor cores, controllers, storage, application-specific units) that need to be interconnected in an efficient and reliable way. The Network-on-Chip (NoC...

Consensus algorithms are an important building block for fault-tolerant distributed systems. This paper investigates approaches to optimize solutions of distributed consensus to the properties of embedded systems. We discuss alternatives that allow constructing better practical solutions in realistic environments. For example, many networked embedded systems are equipped with both ad-hoc commun...

Run-time reconfigurable approaches for FPGAs are gaining interest as they enlarge the design space for system implementation by sequential execution of temporally exclusive system parts on one or several FPGA resources. In [7], we introduced a novel methodology and a design tool for communication synthesis in reconfigurable embedded systems. In [5], this work was extended by a hierarchical reco...
