Abstract
Various embodiments of methods and systems for controlling and/or managing thermal energy generation on a portable computing device that contains a heterogeneous multi-core processor are disclosed. Because individual cores in a heterogeneous processor may exhibit different processing efficiencies at a given temperature, thermal mitigation techniques that compare performance curves of the individual cores at their measured operating temperatures can be leveraged to manage thermal energy generation in the PCD by allocating and/or reallocating workloads among the individual cores based on the performance curve comparison.
