NOC-Based Multi-Processor Architecture for Mixed Time-Criticality Applications

In this chapter we define what a mixed-time-criticality system is and what its requirements are. After defining the concepts that such systems should follow, we described CompSOC, which is one example of a mixed-time-criticality platform. We describe, in detail, how multiple resources, such as processors, memories, and interconnect are combined into a larger hardware platform, and especially how they are shared between applications using different arbitration schemes. Following this, the software architecture that transforms the single hardware platform into multiple virtual execution platforms, one per application, is described.
