Abstract

Software transactional memory (STM) is used to control access to shared resources. The worst case response time (WCRT) estimation is different from the classical preemptive or nonpreemptive model due to its abort-restart nature. In this paper, we derive a WCRT for a STM system using lazy conflict detection. A WCRT example is also given.
