Abstract
Whether through smartphones, portable game consoles, or high performances computing, Systems-on-Chip (SoC) have seen their use widely spread over the last two decades. This can be explained by the low power consumption of these circuits with the regard of the performances they are able to deliver, and the numerous function they can integrate. Since SoC are improving every day, they require better performances from interconnects that support their communications. In order to address this issue Network-on-Chip have emerged.In addition to ASICs, FPGA circuits are one of the possible choices when conceiving a SoC. Our first contribution was therefore to perform and study the performance of Hermes NoC initially designed for ASIC, on reconfigurable circuit. This allowed us to confirm that the architecture of the interconnection system must be adapted to that of the circuit in order to achieve the best possible performances. Thus, our second contribution was to design TrustNoC, an optimized NoC for FPGA platform, with low latency, high operating frequency, and a moderate quantity of logical resources required for implementation.Security is also a primordial aspect of systems-on-chip, and more generally, of all digital systems. Our latest contribution was to study the threats that target SoCs during all their life cycle, then to develop and integrate hardware security mechanisms to TrustNoC in order to counter IP hijacking, and software attacks. During the design of security mechanisms, we tried to limit as much as possible the overhead on NoC performances.
