<p><P>PROBLEM TO BE SOLVED: To ensure the reception of commands in an electric component control means by curtailing the number of the commands to be transmitted to the electric component control means from a game control means. <P>SOLUTION: In a display control means, a command receiving buffer of a ring buffer type is used as such for housing a display control command received from the main board where the game control means is placed. The command receiving buffer is constituted of a plurality of reception command buffers. A frequency of command reception counter is used to indicate where the command received is housed. Even when the data reading processing from the command receiving buffer is delayed, no overwriting is required on the command receiving buffer by a command newly received or no command from the game control means is vanished. In addition, the form of the commands to other control means from the game control means is made common, thereby curtailing the number of the commands. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
