As the complexity of Systems-on-Chip (SoC) is growing, meeting real-time requirements is becoming increasingly difficult. Predictability for computation, memory and communication components is needed to build real-time SoC. We focus on a predictable communication infrastructure called the Æthereal Network-on-Chip (NoC). TheÆthereal NoC is a scalable communication infrastructure based on routers and network interfaces (NI). It provides two services: guaranteed throughput and latency (GT), and best effffffort (BE). Using the GT service, one can derive guaranteed bounds on latency and throughput. To achieve guaranteed throughput, buffffffers in NI must be dimensioned to hide round-trip latency and rate difffffference between computation and communication IPs (Intellectual Property). With the BE service, throughput and latency bounds cannot be derived with guarantees. In this chapter, we describe an analytical method to compute latency, throughput and buffffffering requirements for the Æthereal NoC. We show the usefulness of the method by applying it on an MPEG-2 (Moving Picture Experts Group) codec example.
