Abstract: A system and method for controlling processor instruction execution. In one example, a method for synchronizing a number of instructions performed by processors includes instructing a first processor to iteratively execute instructions via a first set of iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the first set of iterations is less than a number of instructions executed in a prior iteration of the first set of iterations. The method also includes instructing a second processor to iteratively execute instructions via a second set of iterations until the predetermined time period has elapsed. A number of instructions executed in each iteration of the second set of iterations is less than a number of instructions executed in a prior iteration of the second set of iterations. The method includes determining whether additional instructions are to be executed.
