An abstract design for a complex machine may include components like Fast Fourier Transform, Convolution, etc. Operad morphisms can describe the decomposition of the system into subcomponents. and their detailed interconnections (wiring, software plumbing). Were it to be interpreted in hardware alone, the composition of the hierarchy of morphisms could yield a detailed circuit diagram comprising a large number of logic gates.
