用自旋波技术实现波流水线
Achieving Wave Pipelining in Spin Wave Technology
摘要：
就其本质而言，电压/电流激发的自旋波（SW）通过波导传播而不消耗明显的功率。如果SW激励是通过向输入端连续施加电压/电流来执行的（通常是这种情况），则总能耗由换能器功率和电路关键路径延迟决定，这会由于SW缓慢而导致高能耗。然而，如果换能器在脉冲中操作，则能量变得与电路延迟无关，并且它主要由换能器功率和延迟确定，因此脉冲操作应该是目标。在本文中，我们利用一个三输入的多数门（MAJ）来研究连续模式操作（CMO）和脉冲模式操作（PMO）。此外，我们通过微磁学模拟验证了CMO和PMO三输入择多门。此外，我们评估和比较CMO和PMO多数门实现的能量。结果表明，PMO减少MAJ门的能量消耗的一个因素的18。此外，我们描述了如何PMO可以打开的道路，利用波流水线（WP）的概念在SW电路。我们验证WP的概念，通过微磁模拟，我们评估其影响的吞吐量。我们的评估表明，由四个级联的MAJ门WP形成的电路的吞吐量增加了3.6倍。
英文摘要：
By their very nature, voltage/current excited Spin Waves (SWs) propagate through waveguides without consuming noticeable power. If SW excitation is performed by the continuous application of voltages/currents to the input, which is usually the case, the overall energy consumption is determined by the transducer power and the circuit critical path delay, which leads to high energy consumption because of SWs slowness. However, if transducers are operated in pulses the energy becomes circuit delay independent and it is mainly determined by the transducer power and delay, thus pulse operation should be targeted. In this paper, we utilize a 3-input Majority gate (MAJ) to investigate the Continuous Mode Operation (CMO), and Pulse Mode Operation (PMO). Moreover, we validate CMO and PMO 3-input Majority gate by means of micromagnetic simulations. Furthermore, we evaluate and compare the CMO and PMO Majority gate implementations in term of energy. The results indicate that PMO diminishes MAJ gate energy consumption by a factor of 18. In addition, we describe how PMO can open the road towards the utilization of the Wave Pipelining (WP) concept in SW circuits. We validate the WP concept by means of micromagnetic simulations and we evaluate its implications in term of throughput. Our evaluation indicates that for a circuit formed by four cascaded MAJ gates WP increases the throughput by 3.6x.
