System for controlling low order device

Abstract

Abstract PURPOSE:To speed up an interrupting processing without imposing a big burden on a low-order central processor by providing a signal line for transmitting an interrupting signal from a low-order device to the low-order central processor to a bus adapter part between the low-order device and the bus adapter part. CONSTITUTION:The signal line 7 for transmitting the interrupting signal transmitted from the low-order device 6 to the low-order central processor 5 to the bus adapter part 3 between the low-order device 6 and the bus adapter part 3. Consequently, the interrupting signal from the low-order device 6 is appropriately processed by the command of the high-order central processor 1 and the like according to whether the high-order central processor 1 or the low-order central processor 5 has instructed of starting even if the low-order central processor 5 does not judge the device which has instructed of starting. Thus, the interrupting processing can be executed without imposing the big burden on the low-order central processor 5.
