A hardware controller includes a first hardware interface, a second hardware interface, first hardware logic, and second hardware logic. The first hardware interface is to couple the hardware controller to hardware entities of a hardware device in which the hardware controller is to be included. The second hardware interface is to couple the hardware controller to a memory to receive instructions. The first hardware logic is to choose a selected hardware entity from the hardware entities. The second hardware logic is to execute the instructions in relation to the selected hardware entity.
