Process variations in advanced nodes introduce significant core-to-core performance differences in single-chip multi-core architectures. Isolating each core with its own frequency and voltage island helps improving the performance of the multi-core architecture by operating at the highest frequency possible rather than operating all the cores at the frequency of the slowest core. However, inter-core communication suffers from additional cross-clock-domain latencies that can offset the performance benefits. This work proposes the concept of the configurable, variable-size frequency and voltage domain, and it is described in the context of a tile-based, massive multi-core architecture.
