  In recent years, the field of Deep Learning has seen many disruptive and
impactful advancements. Given the increasing complexity of deep neural
networks, the need for efficient hardware accelerators has become more and more
pressing to design heterogeneous HPC platforms. The design of Deep Learning
accelerators requires a multidisciplinary approach, combining expertise from
several areas, spanning from computer architecture to approximate computing,
computational models, and machine learning algorithms. Several methodologies
and tools have been proposed to design accelerators for Deep Learning,
including hardware-software co-design approaches, high-level synthesis methods,
specific customized compilers, and methodologies for design space exploration,
modeling, and simulation. These methodologies aim to maximize the exploitable
parallelism and minimize data movement to achieve high performance and energy
efficiency. This survey provides a holistic review of the most influential
design methodologies and EDA tools proposed in recent years to implement Deep
Learning accelerators, offering the reader a wide perspective in this rapidly
evolving field. In particular, this work complements the previous survey
proposed by the same authors in [203], which focuses on Deep Learning hardware
accelerators for heterogeneous HPC platforms.
