Security has gained increasing relevance in the development of embedded devices. Towards the aim of a secure system at each level of the design, in this paper we address security aspects related to networks-on-chips (NoCs) architectures. After presenting the attacks most likely to address NoCs, we survey existing academic and industrial secure architectures(More)
The Square Kilometre Array (SKA) will be the most sensitive radio telescope in the world. This unprecedented sensitivity will be achieved by combining and analyzing signals from 262,144 antennas and 350 dishes at a raw datarate of petabits per second. The processing pipeline to create useful astronomical data will require hundreds of peta-operations per(More)
As CMOS technology scales down into the deep-submicron domain, the aspects of fault tolerance in complex Networks-on-Chip (NoCs) architectures are assuming an increasing relevance. Task remapping is a software based solution for dealing with permanent failures in processing elements in the NoC. In this work, we formulate the optimal task mapping problem for(More)
—Security is gaining relevance in the development of embedded devices. Toward a secure system at each level of design, this paper addresses security aspects related to Network-on-Chip (NoC) architectures, foreseen as the communication infrastructure of next-generation embedded devices. In the context of NoC-based multiprocessor systems, we focus on the(More)
Security issues are emerging to be a basic concern in modern SoC development. Since in the field of on-chip interconnections the security problem continues to remain mostly an unexplored topic, this paper proposes a novel technique for data protection that uses the communication subsystem as basis. The proposed architecture works as a firewall managing the(More)
Networks-on-Chip (NoCs) have appeared as design strategy to overcome the limitations, in terms of scalability, efficiency, and power consumption of current buses. In this paper, we discuss the idea of using NoCs to monitor system behaviour at run-time by tracing activities at initiators and targets. Main goal of the monitoring system is to retrieve(More)

The MADNESS project aims at the definition of innovative system-level design methodologies for embedded MP-SoCs, extending the classic concept of design space exploration in multi-application domains to cope with high heterogeneity, technology scaling and system reliability. The main goal of the project is to provide a framework able to guide designers and(More)
