A system chip includes a plurality of processing elements for performing primary computations of a plurality of tasks, a plurality of non-processing elements for controlling flow of data associated with the tasks among the processing elements, and a main controller including a scheduler, a resource allocation module, and a power management module. The scheduler assigns the tasks on the processing and non-processing elements with reference to time parameters of the processing and non-processing elements. The resource allocation module controls operations of the processing and non-processing elements with reference to task assignments determined by the scheduler. The power management module performs dynamic voltage management upon the processing and non-processing elements according to the scheduled tasks.
