Designs of asynchronous networks-on-chip are of growing interest because a complete asynchronous implementation can solve the synchronization problems of large networks. However, asynchronous circuits suffer from the lack of proper design flows because their functionality often relies on timing constraints, which are not extensively supported by common CAD synthesis tools. This paper proposes the design and implementation of an asynchronous router architecture suitable for a network-on-chip in the context of a Vision-System-on-Chip. The developed design flow for the synthesis of asynchronous bundled-data pipelines is based on common synthesis tools and, therefore, enables high compatibility with synchronous designs and a low barrier to entry.
