A Memristor‐Based In‐Memory Computing System‐on‐Chip with Efficient Depthwise Convolution
Advanced Intelligent Systems, EarlyView.We present a memristor‐based in‐memory computing (IMC) architecture that enables efficient depthwise convolution (DWC) acceleration. Fabricated in a system‐on‐chip with crossbar arrays, the design improves memory utilization. Experimental validation demonstrates the first hardware acceleration of DWC in IMC, achieving a digital comparable inference ...

Business Strategy and the Environment, EarlyView.ABSTRACT Firms' strategic decision‐making relies not only on their own information but also on that disclosed by supply chain partners. While research recognizes buyers' importance in green innovation, the impact of their information disclosure remains underdeveloped. Drawing on the extended resource‐based view, this study investigates the joint effect
