Overcoming single-thread performance hurdles in the core fusion reconfigurable multicore architecture

Though the prime target of multicore architectures is parallel and multithreaded workloads (which favors maximum core count), executing sequential code fast continues to remain critical (which benefits from maximum core size). This poses a difficult design trade-off. Core Fusion is a recently-proposed reconfigurable multicore architecture that attempts to circumvent this compromise by "fusing" groups of fundamentally independent cores into larger, more aggressive processors dynamically as needed. In this way, it accommodates highly parallel, partially parallel, multiprogrammed, and sequential codes with ease.
