FIELD: physics, computation hardware.
SUBSTANCE: invention relates to multiprocessor computation media, particularly, to transaction processing inside such computation media. Instruction "start the transaction" initiation of transaction execution and initiates the mask of saving of general purpose registers containing bits which if set specify the registers to be saved in the case of transaction reset. At the start of transaction content of registers is saved in the memory not accessible for the program and is said transaction is reset, saved content is copied into registers.
EFFECT: higher rate of execution of transaction start instruction owing to the content of those registers specified directly by said saving mask.
