Speculative execution
Through the interpretation and execution may need to advance the program instruction way to improve execution speed: when the processor executes instructions (each five), using the method of "speculation". This can make the Pentium II processor super processing capacity into full play, so as to enhance the performance of software. By processing software commands is based on speculation branch basis, so the results as the "prediction" keep up. Once the final state can be determined, the instruction will be returned to its normal order and maintain a permanent state of the machine
