<P>PROBLEM TO BE SOLVED: To provide a CPU board capable of increasing the number of interface pins usable by a user while maintaining a shape of VME standards. <P>SOLUTION: In a CPU board in which a master board with a CPU 13 mounted thereon is in a shape of VME standards and has a connector (interface pins) for connecting a slave board thereto, the allocation of the interface pins of the connector is changed from VME standards, and a main bus 12 for controlling slave units S1-S17 uses only an SPI bus for mounting, thereby significantly reducing the number of data buses and control buses to the slave board and increasing the number of the interface pins usable by a user. <P>COPYRIGHT: (C)2012,JPO&INPIT |
