Contention for critical sections can reduce performance and scalability by causing thread serialization. The proposed accelerated critical sections mechanism reduces this limitation. ACS executes critical sections on the high-performance core of an asymmetric chip multiprocessor (ACMP), which can execute them faster than the smaller cores can.
