Abstract

PURPOSE:To highly speedily read timer values which are in common and mutual times are coincident, and to easily realize logic construction to have no contradiction in lock control by providing a bus to directly inform respective processors of the timer value from a timer device to be common to the respective processors. CONSTITUTION:A timer device 20 is provided to be peculiar in a system and a bus 70 is provided to connect a timer device 20 and all processors 1-4 and to transfer the timer information of the timer device 20 to the processors 1-4. The processors 1-4 have a means to read the timer value sent by the bus 70. Then, respective operating systems add the timer value to journal information. Thus, the operating systems of the respective processors 1-4 can highly speedily read the timer values which are in common among the respective processors 1-4 and the mutual time are coincident.
