磁跑道的时间记忆
Temporal Memory with Magnetic Racetracks
摘要:
竞争逻辑是一种相对定时代码,其表示一组导线上的数字边缘的波前中的信息,以便加速动态编程和机器学习算法。Skyrmions,气泡和畴壁是移动磁配置(孤子)与布尔数据存储的应用程序。我们建议使用这些孤子的电流感应位移的磁赛道作为本机的时间存储器的种族逻辑计算。本地同步的赛道可以在空间上存储数字边缘的相对定时,并提供非破坏性的读出。skyrmion运动的线性运动学,所提出的设备的可调谐性和低电压异步操作,以及消除任何需要恒定skyrmion成核,使这些磁赛道的自然记忆低功耗,高吞吐量的种族逻辑应用。
英文摘要:
Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic configurations (solitons) with applications for Boolean data storage. We propose to use current-induced displacement of these solitons on magnetic racetracks as a native temporal memory for race logic computing. Locally synchronized racetracks can spatially store relative timings of digital edges and provide non-destructive read-out. The linear kinematics of skyrmion motion, the tunability and low-voltage asynchronous operation of the proposed device, and the elimination of any need for constant skyrmion nucleation make these magnetic racetracks a natural memory for low-power, high-throughput race logic applications.
