耦合振荡器为解决计算机视觉中的各种计算密集型问题提供了一种有效的非布尔范式。这促使低功率耦合振荡器的大型网络的实现。在这项工作中，我们实验证明：（1）一个基于二氧化钒（VO_2）绝缘体-金属跃迁（IMT）的弛张振荡器，其最低直流输入（峰值）功率为~23 μW;（ii）具有记录数量的元件的耦合的VO 2振荡器的网络（6个振荡器）其在高维空间中执行图像处理功能，如颜色检测和诸如膨胀和腐蚀的形态学操作）。校准模拟表明，在等吞吐量下，与32 nm CMOS加速器相比，功耗降低了10倍。
Coupled oscillators provide an efficient non-Boolean paradigm for solving a variety of computationally intensive problems in computer vision. This motivates the realization of large networks of low-power coupled oscillators. In this work, we experimentally demonstrate: (i) a relaxation oscillator based on the insulator-metal transition (IMT) in vanadium dioxide (VO2) with record low DC input (peak) power of ~23 μW; (ii) a network of coupled VO2 oscillators with record number of elements (6 oscillators) which perform image processing functionalities in high dimensional space like color detection and morphological operations such as dilation and erosion). Calibrated simulations show that 10× reduction in power compared to a 32 nm CMOS accelerator at iso-throughput.
