Abstract: A method for controlling a task migration of a task in a heterogeneous multi-core system having at least a first cluster and a second cluster is provided. The method may include at least the following steps: dynamically adjusting a migration threshold; comparing a load of the task running on one core of the first cluster with the migration threshold, and accordingly generating a comparison result; and selectively controlling the task to migrate to the second cluster according to at least the comparison result, wherein each core in the first cluster has first processor architecture, and each core in the second cluster has second processor architecture different from the first processor architecture.
