Artificial Intelligence (AI) has witnessed remarkable growth, particularly
through the proliferation of Deep Neural Networks (DNNs). These powerful models
drive technological advancements across various domains. However, to harness
their potential in real-world applications, specialized hardware accelerators
are essential. This demand has sparked a market for parameterizable AI hardware
accelerators offered by different vendors.
Manufacturers of AI-integrated products face a critical challenge: selecting
an accelerator that aligns with their product's performance requirements. The
decision involves choosing the right hardware and configuring a suitable set of
parameters. However, comparing different accelerator design alternatives
remains a complex task. Often, engineers rely on data sheets, spreadsheet
calculations, or slow black-box simulators, which only offer a coarse
understanding of the performance characteristics.
The Abstract Computer Architecture Description Language (ACADL) is a concise
formalization of computer architecture block diagrams, which helps to
communicate computer architecture on different abstraction levels and allows
for inferring performance characteristics. In this paper, we demonstrate how to
use the ACADL to model AI hardware accelerators, use their ACADL description to
map DNNs onto them, and explain the timing simulation semantics to gather
performance results.

人工智能通过深度神经网络持续增长，为了充分发挥其潜力，特定的硬件加速器成为必需品。本文介绍了如何使用抽象计算机体系结构描述语言（ACADL）对人工智能硬件加速器进行建模，并使用它们的描述将深度神经网络映射到加速器上，进而解释时间模拟语义来获取性能结果。
