Extended recursive analysis for tilera tile64 NoC architectures: towards inter-NoC delay analysis

International audienceA heterogeneous network, where a switched-Ethernet backbone, e.g. AFDX, interconnects several end systems based on Network-on-Chip (NoC), is a promising candidate to build new avionics architectures. When using such a heterogeneous network for real-time applications, a global worst-case traversal time (WCTT) analysis is needed. In this short paper we focus on the intra-NoC communication on a Tilera TILE64-like NoC. First, we extend the Recursive Calculus (RC) to achieve tighter intra-NoC WCTT. Then, we explain how this intra-NoC WCTT analysis could be used in a compositional manner for the end-to-end inter-NoC delay analysis
