PURPOSE:To constitute a high-speed serial data transfer line by connecting plural microprocessor systems by a looped data transmission line when the microprocessor systems are used and transmit and receive data to one another. CONSTITUTION:Microprocessor systems (A)101-(n)10n as (n) microprocessor systems are mutually connected in a loop shape by a data transmission line CH and a receiving node select signal line L. IN regard to the microprocessor, only the desired receiving node receives the data by sending a receiving node select signal S specifying a receiving node as a previously set state through the receiving node select signal line L in the previously set state; and other nodes are bypassed to eliminate the need for data reception, thereby speeding up the data transfer. |
