Abstract

High-Level Synthesis (HLS) tools that compile algorithms written in high-level languages into register-transfer level implementations can significantly improve design productivity and lower engineering cost. However, HLS-generated designs still lag handwritten implementations in a number of areas, particularly in the efficient allocation of hardware resources. In this work, we propose the use of dynamic dependence analysis to generate higher quality designs using existing HLS tools. We focus on resource sharing for compute-intensive workloads, a major limitation of relying only on static analysis. We demonstrate that with dynamic dependence analysis, the synthesized designs can achieve an order of magnitude resource reduction without performance loss over the state-of-the-art HLS solutions.
