At the end of the day, all programs are just sequences of machine instructions or VM byte-code (which is essentially the same thing as there is an isomorphism between the two) that perform transformations on data in memory (registers, RAM, disk storage, etc.)
The CPU doesn't give a rats ass if your program was originally written in an imperative or declarative language. All it cares is that it has a sequence of instructions to execute. Most machine languages are imperative themselves as CPUs are essentially state machines.
