An Open-Source Tool for Generating Domain-Specific Accelerators for Resource-Constrained Computing

Domain-specific accelerators (DSAs) are crucial in modern computer architecture as they enable highly efficient processing for specialized tasks, significantly improving performance and energy efficiency over general-purpose computing systems. Previous work introduced the _Superblock_ (SB) as a new granularity for designing DSAs. The SB provides a middle ground to the existing extreme granularities of creating DSAs only from Basic Blocks (BBs) or whole functions. This paper describes an Open Source Software (OSS) tool called **D2** that implements the SB approach and will enable researchers and developers in the DSA community to easily experiment with this new granularity towards finding an optimal solution to the DSA definition at hand. Our results show that the SB should be taken seriously as a candidate for creating DSAs.
