Blade-OC Asynchronous Resilient Template ‡ This research has been supported in part by NSF Grant #1619415.

This paper introduces a novel timing-resilient asynchronous bundled-data template called Blade-OC. The template replaces the synchronous global clock driving FFs with asynchronous controllers that drive error-detecting latches. Compared to its predecessors, the template supports a larger timing resiliency window (TRW) enabling higher performance for designs with wide variations in delay, such as seen in near and subthreshold computing. This paper quantifies this performance improvement for a variety of pipeline structures assuming lognormal datapath delay distributions.
