项目摘要
Not all computing problems are created equal. At the heart of many, increasingly important, applications ranging from the design of intelligent machines that can explain their decisions, to electronic design automation for tamper-proof integrated circuits, lies a class of combinatorial optimization problems that remain an unconquered bastion of traditional digital computing. As a case in point, solving the archetypal Boolean satisfiability problem, integral to many such applications, requires exponentially increasing energy and computation time that makes its practical deployment at large scales unfeasible. The proposed research aims to address this challenge through a cohesive across-the-stack effort that spans from the formulation of a physics-inspired computational model to designing a supporting hardware ecosystem that encompasses novel engineered materials and devices, circuits, and their subsequent system integration. The foundational principle of the Ferroelectric-based Compute-in-Memory Dynamical Engine (FerroCoDE) is based on exploiting the inherent efficiency of physical phenomena in nature (namely, maximization of entropy production) by creating unique synergies between physics and computation. To execute these computational models efficiently, the team of researchers is developing a new hardware platform that converges the unique capabilities of dynamical systems with compute-in-memory architectures, enabled through fundamental innovation in ferroelectric materials and their device functionalities. The FerroCoDE platform will enable orders-of-magnitude improvement in computational efficiency enabling the deployment of relevant applications at a scale and in (energy-constrained) environments that are presently challenging to achieve using present day computers. Furthermore, to broaden the impact of this work, the team will develop a publicly accessible online platform, OscWorks, for applying oscillator-based computing in education and research. Additionally, the team will engage with K-12 and undergraduate students through various initiatives such as workshops, online seminars, and research opportunities.The systems challenge that is being addressed by this ASCENT project is to design, fabricate and demonstrate a Ferroelectric Hafnium Oxide (HfO2) based Compute-in-Memory (CiM) Dynamical Engine (FerroCoDE) that leverages the rich non-linear analog dynamics of oscillators in conjunction with the area and energy efficiency of ferroelectric CiM architecture to accelerate the computationally hard maximum satisfiability problem. The FerroCoDE exploits a novel formulation of the satisfiability problem as the direct maximization of entropy in the compute engine which is being developed through a vertically integrated materials-to-systems effort that focusses on: (i) Development of phase- and crystallographic-texture-engineered HfO2-based ultra-thin ferroelectric and antiferroelectric films with tunable properties; (ii) Design and fabrication of a novel non-volatile 1FeFET-1FTJ memory cell and array to enable in-memory programming and evaluation of the satisfiability clauses; and energy efficient AFE oscillator arrays (iii) Building synergistic convergence between the hardware and algorithm; (iv) System engineering, with emphasis on developing learning algorithms to optimize dynamical system initialization, development of annealing schedules and hardware scalability. (v) Development and demonstration of a FerroCoDE prototype on PCB.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
并不是所有的计算问题都是平等的。在许多日益重要的应用中,从能够解释其决策的智能机器的设计,到防篡改集成电路的电子设计自动化,都存在着一类组合优化问题,它们仍然是传统数字计算不可征服的堡垒。作为一个典型的例子,解决原型布尔可满足性问题,对于许多这样的应用来说,需要指数级增加的能量和计算时间,这使得它在大规模的实际应用中是不可行的。这项拟议的研究旨在通过跨堆栈的凝聚力来应对这一挑战,该工作涵盖从物理启发的计算模型的制定到设计包含新型工程材料和器件、电路及其后续系统集成的支持性硬件生态系统。基于铁电的内存计算动态引擎(FerroCoDE)的基本原理是基于通过在物理和计算之间创建独特的协同效应来开发自然界中物理现象的固有效率(即,最大化熵产生)。为了有效地执行这些计算模型,研究团队正在开发一种新的硬件平台,该平台通过铁电材料及其器件功能的根本性创新,将动力系统的独特能力与内存计算架构融合在一起。FerroCoDE平台将在计算效率方面实现数量级的改进,从而能够在(能源受限的)环境中大规模部署相关应用程序,而这些应用程序目前使用当今的计算机很难实现。此外,为了扩大这项工作的影响,该小组将开发一个公众可访问的在线平台OscWorks,用于在教育和研究中应用基于振荡器的计算。此外,该团队将通过各种活动,如研讨会、在线研讨会和研究机会,与K-12和本科生接触。该提升项目正在解决的系统挑战是设计、制造和演示基于铁电Hafnium氧化物(HfO2)的内存计算(CIM)动态引擎(FerroCoDE),该引擎利用振荡器丰富的非线性模拟动力学结合铁电CIM架构的面积和能源效率来加速计算困难的最大可满足性问题。FerroCoDE使用可满足性问题的新公式作为计算引擎中的熵的直接最大化,该计算引擎通过垂直集成的材料到系统的努力而被开发,该工作集中于:(I)开发具有可调特性的相和晶体织构工程的基于HfO2的超薄铁电和反铁电薄膜;(Ii)设计和制造新型非易失性1FeFET-1FTJ存储单元和阵列以实现存储器内编程和可满足性子句的评估;以及节能AFE振荡器阵列(Iii)在硬件和算法之间建立协同收敛;(4)系统工程,重点是开发学习算法以优化动态系统初始化、制定退火表和硬件可伸缩性。(V)在多氯联苯上开发和演示FerroCoDE原型。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
