Emerging advanced System-on-Chip (SoC) designs contain more and more complicated functions to be accelerated. This presents a challenge to conventional design approaches which use different hardware architectures or separate hardware accelerators to implement the various functions. To tackle this challenge, for the first time, we propose a generalized hardware accelerator called “Huicore” to speed up diverse functions on the same substrate. Through the analysis and transformation of mathematical characteristics, we reveal the commonality of many complicated functions using the CORDIC algorithm. Then we explore a reconfigurable architecture to implement them. The proposed reconfigurable accelerator can not only accelerate the implementation of many complicated functions, but also has small area, low power consumption and high precision. It is very suitable for integration in a SoC system to accelerate the implementation of various applications.

汇芯：复杂功能的通用硬件加速器

新兴的高级片上系统 (SoC) 设计包含越来越复杂的需要加速的功能。这对使用不同硬件架构或单独的硬件加速器来实现各种功能的传统设计方法提出了挑战。为了应对这一挑战，我们首次提出了一种名为“Huicore”的通用硬件加速器，以加速同一基板上的各种功能。通过对数学特征的分析和变换，我们揭示了许多复杂函数使用CORDIC算法的共性。然后我们探索一种可重构的架构来实现它们。所提出的可重构加速器不仅可以加速许多复杂功能的实现，而且具有面积小、功耗低、精度高等特点。
