Abstract—Hierarchical Agent Architecture is proposed to provide online monitoring services to NoC-based systems. Based on circuit conditions traced at the run-time, system settings are monitored adaptively by agents at each architectural level. This monitoring approach partitions various online diagnostic and management services onto hierarchical implementation levels so as to provide scalability and variability for large-scale NoC design. This paper explains the monitoring interaction between agent levels, and focuses on system optimization alternatives handled by different agent levels. It further quantitatively analyzes the feasibility and design alternatives in monitoring communication interconnection upon regular tile-based NoC layout. Though still under intensive research, the proposed architecture is endowed with promising potential for highly-integrated NoC design. I.
