FIELD: information technology.
SUBSTANCE: invention relates to device and method of increasing efficiency of parallel execution of program transactions when executing speculative critical sections within transactional memory architecture. Perform speculative critical section to complete regardless of whether the lock is retained by another transaction at the beginning or during speculative critical section. As soon as the design speculative critical section has been completed, the lock is captured. If the lock is not captured, the completion of speculative critical section. If the lock is captured, the interruption speculative critical section.
EFFECT: providing parallel executing program transactions and one or more hardware transactions, which is achieved due to establishment of lock at the start of execution of critical section and control of the lock is installed at the end of critical section.
