MachSuite: Benchmarks for accelerator design and customized architectures

Recent high-level synthesis and accelerator-related architecture papers show a great disparity in workload selection. To improve standardization within the accelerator research community, we present MachSuite, a collection of 19 benchmarks for evaluating high-level synthesis tools and accelerator-centric architectures. MachSuite spans a broad application space, captures a variety of different program behaviors, and provides implementations tailored towards the needs of accelerator designers and researchers, including support for high-level synthesis. We illustrate these aspects by characterizing each benchmark along five different dimensions, highlighting trends and salient features.
