Abstract
PURPOSE: To increase greatly the retry enable range by trying the order retry through setting of the FF showing the possibility of the retry in case no success is secured although the microorder retry is carried out in the prescribed frequency.
CONSTITUTION: In case some fault occurs while the process is carried out, the state of the hardware is released to the state same as that immediately before occurrence of the error. And the contents of registers 3 and 12 are released to registers 1 and 11 respectively. Thus the success is decided for the microorder retry if no hardware error occurs again. If some error occurs, the execution is given in the prescribed frequency. And the success is not obtained yet, the order retry is given. In other words, the checking is given whether FF6 showing the possibility of retry is set or not. And the order retry is given in case FF6 is set; while the interruption code is set if FF6 is not set to perform the machine check interruption. As a result, the retry enable range can be increased greatly.
