The interconnection of many-cores by an avionics full duplex switched Ethernet network (AFDX) is envisioned for future avionics architecture. The principle is to distribute avionics functions on these many-cores. Many-cores are based on simple cores interconnected by a Network-on-Chip (NoC). The allocation of functions on the available cores as well as the transmission of flows on the NoC has to be performed in such a way that avionics timing constraints are never violated. Several theoretical solutions have been proposed for this distribution. However they have not been evaluated on real architectures. In this paper we introduce a framework for the prototyping of such implementations. This framework is based on the existing ProNoC tool which allows the configuration of an FPGA as a NoC. The goal is to be able to compare distribution solutions with different NoC features in terms of scheduling or routing.
