System and method for executing tasks according to a selected scenario in response to probabilistic power consumption information of each scenario

A processing device comprising:

• one or more processing modules for executing a plurality of tasks, said processing subsystems executing a power management function for;
• generating a plurality of scenarios for executing a plurality of tasks scheduled for concurrent execution;
• calculating consumption information for said plurality of scenarios, the consumption information of each scenario based on probabilistic values for activities associated with the tasks;
• controlling the execution of the tasks according to a selected one of said plurality of scenarios on said processing modules responsive to said consumption information.

A method for controlling the concurrent execution of tasks in a processor comprising a plurality of processing modules, comprising the steps of:

• calculating consumption information based on probabilistic values for activities associated with the tasks by:
• generating a task allocation scenario based on a task list describing the tasks to be executed and a task model describing the tasks along with information regarding possible degradations associated with one or more of the tasks in said task list;
• estimating the activities for the task allocation scenario;
• and
• computing the consumption associated with said activities;
• and
• executing the tasks on said plurality of processing modules responsive to said consumption information.
