Accelerating Critical Section Execution with Asymmetric Multicore Architectures

The proposed accelerated critical sections mechanism reduces this limitation by executing critical sections on the high-performance core of an asymmetric chip multiprocessor, which can execute them faster than the smaller cores can.

Abstract

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.
