Extração de dados e monitoramento de eventos na rede Intra-Chip Brnoc

Abstract

With the continuous increase in transistor density in integrated circuits, circuits with greater complexity become possible, such as System on Chip (SoC). multiple microprocessors, on-chip systems with multiple processors arise Multiprocessor System-on-Chip (MPSoC). In MPSoCs, buses become a limitation, which brings us Networkon Chip intra-chip networks (NoC). The Broadcast Network on Chip (BrNoC) (WACHTER et al., 2017) is a NoC network that, being a recent one, does not yet have a specially developed debugging tool. In this work, the objective was to implement a graphical interface for monitoring events in simulations of the BrNoC network, in order to contribute to the study of intra-chip networks with Broadcast support. Among the activities carried out in the development of the work are: the instrumentation of the code in the Hardware description layer with mechanisms for extracting data and capturing events; the definition of a communication standard between the tool layers; and the availability of a graphical interface for analyzing the information collected. As a result of the proposed implementation, it can be observed that, despite its simplicity, it ends up being robust, as it does not ignore any signal and operates, regardless of the state of the router’s state machines, collecting the signals that have changed values, thus allowing , monitor the entire state of the networkanditsrouters.
