Integrating Approximate Logic Synthesis into Approximate High-Level Synthesis

Approximate high-level synthesis (HLS) and approximate logic synthesis (ALS) are two techniques for generating approximate circuits. They operate at different granularities. Approximate HLS typically modifies instructions in a control and data flow graph, whereas ALS modifies gates and interconnects in a gate-level net...

Timing-driven Approximate Logic Synthesis Based on Cooperative Search

This paper develops two LAC search actions specialized in critical path shortening and area reduction, respectively, and shows that compared to a state-of-the-art area-driven method, this framework further reduces 20% critical path delay with comparable area savings, while being 7.9× faster.
