摘要
本文提出一种由 3 输入和 5 输入多数门构成的节能型基于自旋波(SW)的近似 4:2 压缩器。我们通过微磁模拟验证了该方案,并将其性能与最先进的 SW、45nm CMOS 和 Spin-CMOS 对应方案进行评估和比较。评估结果表明,所提出的压缩器相比其精确 SW 设计版本能耗降低 31.5%。此外,它与带方向耦合器(DC)的近似压缩器具有相同的能耗和错误率,但延迟降低 3 倍。另外,与近似 45nm CMOS 对应方案相比,其能耗降低 14%,而平均错误率低 17%。与其他新兴技术相比,所提出的压缩器在能耗方面比基于近似 Spin-CMOS 的压缩器优出 3 个数量级,同时提供相同的错误率。最后,所提出的压缩器所需的芯片面积(以器件数衡量)最小。
