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.

磁性赛道的时间记忆

竞态逻辑是一种相对时序代码，它表示一组线上数字边缘波前的信息，以加速动态编程和机器学习算法。Skyrmions、气泡和畴壁是具有布尔数据存储应用程序的移动磁性配置（孤子）。我们建议在磁跑道上使用这些孤子的电流感应位移作为用于竞赛逻辑计算的本机时间存储器。本地同步赛道可以在空间上存储数字边缘的相对时间并提供非破坏性读出。斯格明子运动的线性运动学、所提出设备的可调性和低压异步操作，以及不需要恒定的斯格明子成核，使这些磁性跑道成为低功率的自然记忆，
