CHStone

A Suite of Benchmark Programs for C-based High-Level Synthesis


Introduction

The CHStone benchmark suite has been developed for C-based high-level synthesis (HLS). The CHStone benchmark suite selected programs of various application domains, some of which originally belong to other benchmark suites. CHStone has several key features described as follows:

List of Benchmark Programs

The CHStone suite includes the following programs. Source-level characteristics and synthesis results can be found in our paper.
