  Due to their very nature, Spin Waves (SWs) created in the same waveguide, but
with different frequencies, can coexist while selectively interacting with
their own species only. The absence of inter-frequency interferences isolates
input data sets encoded in SWs with different frequencies and creates the
premises for simultaneous data parallel SW based processing without hardware
replication or delay overhead. In this paper we leverage this SW property by
introducing a novel computation paradigm, which allows for the parallel
processing of n-bit input data vectors on the same basic SW based logic gate.
Subsequently, to demonstrate the proposed concept, we present 8-bit parallel
3-input Majority gate implementation and validate it by means of Object
Oriented MicroMagnetic Framework (OOMMF) simulations. To evaluate the potential
benefit of our proposal we compare the 8-bit data parallel gate with equivalent
scalar SW gate based implementation. Our evaluation indicates that 8-bit data
3-input Majority gate implementation requires 4.16x less area than the scalar
SW gate based equivalent counterpart while preserving the same delay and energy
consumption figures.
