论文摘要
Race Logic是一个相对的时机代码，在一组电线上代表数字边缘波前的信息，以加速动态编程和机器学习算法。 Skyrmions，气泡和域墙是带有布尔数据存储的应用程序的移动磁性配置（孤子）。我们建议将这些孤子在磁性赛道上使用电流引起的位移作为种族逻辑计算的天然时间内存。局部同步赛道可以在空间上存储数字边缘的相对时间，并提供无损的读数。 Skyrmion运动的线性运动学，所提出的设备的可调性和低压异步操作，以及消除对持续的Skyrmion成核的任何需求，使这些磁性赛道成为低功率，高促进型逻辑应用的自然记忆。
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.
