Control circuit templates for asynchronous bundled-data pipelines
S. Tugsiriavisut, P.A. Beerel · 2003
This paper proposes the use of templatized asynchronous control circuits with single-rail datapaths to create low-power bundled-data non-linear pipelines. First, we adapt an existing templatized control style for 1-of-N rail pipelines, the Pre-Charged Full Buffer PCFB, to bundled-data pipelines. Then, we present a novel true 4-phase template (T4PFB) that has lower control overhead. Simulation results indicate 12%-44% higher throughput for the pipeline stage equivalent to 8 to 40 gates.
