Spin Waves (SWs), by their nature, are excited by means of voltage driven or current driven cells under two modes: Continuous Mode Operation (CMO), and Pulse Mode Operation (PMO). Moreover, the low throughput of the SW technology (caused by its high latency) can be enhanced by wavepipelining which is supported inherently by the SW under the two modes. Therefore, we propose wavepipelined SW based two cascaded Majority gates (SWMGs) circuit and validate it by means of micromagnetic simulations working under CMO and PMO. Our evaluation results indicate that PMO SWMGs circuit consumes 6.7x less energy than CMO SWMGs circuit. In addition, the evaluation shows that the wavepipelined PMO and CMO SWMGs circuit have the same throughput, while they are better than the non-wavepipelined circuit by 2x.
