摘要： Provided is a method for task migration in an electronic device. The method includes: assigning a task with a specific function to a first group among groups formed according to a preset criterion; assigning the first group to one of first processing units functionally connected to the electronic device; and migrating, when the first group matches preset criteria of second processing units functionally connected to the electronic device, the first group to one of the second processing units. Based on this, it is possible to create various other embodiments.
