A Loosely Synchronizing Asynchronous Router for TDM-Scheduled NOCs
This paper presents an asynchronous router design for use in time-division-multiplexed (TDM) networks-on-chip. Unlike existing synchronous, mesochronous and asynchronous router designs with similar functionality, the router is able to silently skip over cycles/TDM-slots where no traffic is scheduled and hence avoid all switching activity in the idle links and router ports.
In this way switching activity is reduced to the minimum possible amount. The fact that this relaxed synchronization is sufficient to implement TDM scheduling represents a contribution at the conceptual level. The idea can only be implemented using asynchronous circuit techniques. To this end, the paper explores the use of “click-element” templates.
Click-element templates use only flipflops and conventional gates, and this greatly simplifies the design process when using conventional EDA tools and standard cell libraries. Few papers, if any, have explored this.
