<p><P>PROBLEM TO BE SOLVED: To reduce processing burden on a microprocessor. <P>SOLUTION: The power source to the pachinko game machine is turned on. Firstly, the CPU sets the interrupt prohibition and then, sets the interruption mode, the stack pointer and the built-in devices. Then, it is judged whether the backup exists or not along with the parity check. When the backup exists and the result of the checking is normal, the processing of the return to the game state is executed or when no backup exists and the result of the checking is not normal, the initialization processing is executed. Subsequently, the program for setting the random number circuit is executed to set the maximum value of the random numbers, the random number updating system, the cycle of the internal clock signal and the like on the random number circuit. Thereafter, the setting is conducted for the timer and a shift is made to the loop processing. In this manner, after the power source is turned on, the processing for the setting of the random number circuit is carried out before the shift to the loop processing to eliminate the need for the updating processing of the random numbers within the limited interrupt processing time thereby reducing the processing burden on the microprocessor . <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
