<p><P>PROBLEM TO BE SOLVED: To reduce the number of control commands to be transmitted from a game control means to an electric component control means, and to secure the transmission/receiving of commands in the electric component control means. <P>SOLUTION: A ring-buffer type command receiving buffer is used in a display control means as the command receiving buffer for storing a received display control command from a main board in which the game control means is mounted. The command receiving buffer is composed of a plurality of receiving command buffers, and a received command number counter is used to indicate where to store the received command. Even if the process of reading data from the command receiving buffer is delayed, the command in the command receiving buffer is not overwritten by a newly received command, so that the command is not eliminated from the game control means. Furthermore, as the form of the command from the game control means to other control means is common, the number of commands can be reduced. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
