Evaluation of SNMP-like protocol to manage a NoC emulation platform

Abstract

International audience—The Networks-on-Chip(NoCs) are currently the most appropriate communication structure for many-core embedded systems. AnFPGA-based emulation platform can drastically reduce the time needed to evaluate a NoC, even if it is composed by tens or hundreds of distributed components. These components should be timely managed in order to execute an evaluation traffic scenario. There is a lack of standard protocols to drive FPGA-based NoC emulators. Such protocols could ease the integration of emulation components developed by different designers. In this paper, we evaluate a light version of SNMP (Simple Network Management Protocol) to manage an FPGA-based NoC emulation platform. The SNMP protocol and its related components are adapted to a hardware implementation. This facilitates the configuration of the emulation nodes without FPGA-resynthesis, as well as the extraction of emulation results. Some experiments highlight that this protocol is quite simple to implement and very efficient for a light resources overhead
