1. A control system, comprising:
multiple device controllers, wherein each of the multiple device controllers corresponds to at least one processing unit, a hint from an application processor (AP) indicates said each of the multiple device controllers to manage the at least one processing unit; and said each of the multiple device controllers is arranged to receive the hint from the AP, and generate and transmit a control signal to a device root according to the hint, for managing the at least one processing unit via the device root; and
the device root, coupled to the multiple device controllers, and comprising:
a manager, arranged to manage multiple processing units corresponding to the multiple device controllers according to multiple control signals corresponding to the multiple device controllers.
