Abstract
Task migration, an effective resource management approach, contributes to an increase of on-chip communication overhead. We propose an MMPI-based task migration mechanism to lower task migration overhead in NoC-based MPSoC. This task migration mechanism depends on MPSoC message passing interface (MMPI), which defines a parallel programming pattern that program is dependent of task mapping. In the migration mechanism, task state information is transferred to another PE. The migration overhead is lowered since the task migration is based on MMPI and task code is not transferred. Furthermore, the task migration mechanism does not require checkpoints to detect migration request. Experimental results show that the migration delay decreases around 28% without transferring task code.
