This work analyzes the impact of task migration in the context of multiprocessor systems-on-chip, where processors are interconnected by a network-on-chip (NoC) and the system must adapt itself to a dynamic workload, such that performance and real-time constraints are met and energy consumption is minimized. The task migration model assumes that the whole code and data of the tasks are transferred from an origin node to the chosen destination node. Experimental results show that, even with a higher overhead than other possible approaches, task migration may be applied in NoC-based architectures, since it pays off the costs involved in the transfer in terms of overall system performance and energy consumption and may help to improve the fulfillment of task deadlines in soft real-time systems. © 2007 IEEE.
