 Consider a processor executing an instruction. The involved process can be understood as a mechanism whose components are states and combinatory elements in the processor instantiating the functions prescribed by the relevant hardware specifications (specifications for registers, for the Arithmetic Logic Unit etc..), organized in such a way that they are capable of carrying out the observed execution. Providing the description of such a mechanism counts as advancing a mechanist explanation of the observed computation, such as the explanation of an operational malfunction.
