| Abstract | Security is gaining increasing relevance in the development ofembedded devices. Towards a secure system at each level of design,this paper addresses the security aspects related toNetwork-on-Chip (NoC) architectures, foreseen as the communicationinfrastructure of next generation embedded devices. In the contextof NoC-based Multiprocessor systems, we focus on the topic, notthoroughly faced yet, of data protection. We present thearchitecture of a Data Protection Unit (DPU) designed forimplementation within the Network Interface (NI). The DPU supportsthe capability to check and limit the access rights(none, read,write or both) of processors requesting access to data locationsin a shared memory - in particular distinguishing between theoperating roles (supervisor or user) of processing elements. Weexplore different alternative implementations and demonstrate howthe DPU unit does not affect the network latency if the memoryrequest has the appropriate rights. In the experimental section weshow synthesis results for different ASIC implementations of theData Protection Unit. |
