Delay analysis of wormhole based heterogeneous NoC

Abstract

We introduce delay phenomena of a wormhole routing based NoC with variable link capacities and a variable number of virtual channels per link. We also demonstrate how these phenomena can be used to develop a delay analysis. Hence, one can use these phenomena to analyze different heterogeneous NoC architectures and traffic scenarios, which cannot be analyzed by any existing NoC delay analysis. Further details about these phenomena and the delay evaluation methodology can be found in [1].
