摘要:

就其本质而言,自旋波(SW)消耗超低量的能量,这使得它们适用于超低能耗应用。此外,还可以利用压缩器来进一步降低能量消耗并提高乘法器的速度。因此,我们提出了一种新的节能SW基于4-2压缩器,由4个异或门和2个多数门。通过微磁模拟验证了该压缩器的有效性,并与最先进的SW、22 nm CMOS、磁性隧道结(MTJ)、畴壁运动(DWM)和自旋CMOS技术进行了比较。性能评估表明,所提出的压缩器消耗的能量分别比22 nm CMOS和传统SW压缩器少2.5倍和1.25倍,而它消耗的能量比MTJ,DWM和Spin-CMOS设计少至少3个数量级。此外,压缩器实现了最小的芯片面积。总之,我们提出的压缩机的性能评估表明,SW技术有潜力进步的最先进的电路设计的能源消耗和可扩展性方面。

英文摘要:

By their very nature, Spin Waves (SWs) consume ultra-low amounts of energy, which makes them suitable for ultra-low energy consumption applications. In addition, a compressor can be utilized to further reduce the energy consumption and enhance the speed of a multiplier. Therefore, we propose a novel energy efficient SW based 4-2 compressor consisting of 4 XOR gates and 2 Majority gates. The proposed compressor is validated by means of micromagnetic simulations and compared with the state-of-the-art SW, 22nm CMOS, Magnetic Tunnel Junction (MTJ), Domain Wall Motion (DWM), and Spin-CMOS technologies. The performance evaluation shows that the proposed compressor consumes 2.5x less and 1.25x less energy than the 22nm CMOS and the conventional SW compressor, respectively, whereas it consumes at least 3 orders of magnitude less energy than the MTJ, DWM, and Spin-CMOS designs. Furthermore, the compressor achieves the smallest chip real-estate. In summary, the performance evaluation of our proposed compressor shows that the SW technology has the potential to progress the state-of-the-art circuit design in terms of energy consumption and scalability.
