<p>PURPOSE:To execute the correct time synchronization between a time synchronizing control processor and a general processor by holding a time synchronizing mechanism with a time synchronizing control processor, holding a time synchronizing signal receiving mechanism with plural general processors, generating the interruption to a CPU and starting a time synchronizing signal transmitting task and a time synchronizing signal receiving task. CONSTITUTION:A time synchronizing control processor 12 is composed of a bus communicating mechanism 121, a CPU 122 and a time synchronizing mechanism 123, and the time synchronizing mechanism 123 interrupts to the CPU 122 for a constant time, starts a time synchronizing signal transmitting task 124 and transmits the time setting signal from the bus communicating mechanism 121 to a system bus 11. A time synchronizing signal receiving mechanism 133 of a general processor 13, when it receives the time setting signal through a bus communicating mechanism 131, interrupts in a CPU 132, starts a time synchronizing signal receiving task 134 and executes the time synchronizing processing. A general processor 14 and a general processor 15 also execute the time synchronizing processing.</p> |
