摘要：
具有多输出逻辑门节省了很多能量，因为相同的结构可以用于同时馈送下一级门的多个输入。本文提出了一种新颖的三角形扇出的2个自旋波多数和异或门，多数门是由相位检测，而异或门是由阈值检测。所提出的逻辑门通过微磁模拟进行了验证。此外，估计所提出的结构的能量和延迟，并与最先进的自旋波逻辑门，16 nm和7 nm CMOS。结果表明，所提出的结构提供了25%-50%的能量减少相比，其他2-输出自旋波器件，同时具有相同的延迟，和能量减少之间的43倍和0.8倍，当与16 nm和7 nm CMOS相比，同时具有11倍和40倍之间的延迟开销。
英文摘要：
Having multi-output logic gates saves much energy because the same structure can be used to feed multiple inputs of next stage gates simultaneously. This paper proposes novel triangle shape fanout of 2 spin wave Majority and XOR gates; the Majority gate is achieved by phase detection, whereas the XOR gate is achieved by threshold detection. The proposed logic gates are validated by means of micromagnetic simulations. Furthermore, the energy and delay are estimated for the proposed structures and compared with the state-of-the-art spin wave logic gates, and 16nm and 7nm CMOS. The results demonstrate that the proposed structures provide energy reduction of 25%-50% in comparison to the other 2-output spin-wave devices while having the same delay, and energy reduction between 43x and 0.8x when compared to the 16nm and 7nm CMOS while having delay overhead between 11x and 40x.
