Abstract
PURPOSE:To resolve the overhead of the processing of a system controller by interrupting the system controller by a communication request means independently of a trouble detection signal. CONSTITUTION:The decoded result of a micro instruction from a decoder 171 is given to a communication information holding means 110. The output of the means 110 is held in the communication information holding means 110. If there are bits of logical '1' in this held information, logical '1' is given to an update suppressing means 120, and internal information in an arithmetic processing means 100 is frozen while this signal of logical '1' is given. In parallel with this freezing operation, the output of an OR circuit 151 interrupts a system controller 200 as a communication request by a communication request means 140. The controller 200 recognizes the interrupt from the means 140 other than that from a trouble reporting means 133. The controller 200 outputs a signal due to a communication release means 150 in response to this interrupt from the means 140 to release the suppression state due to the means 120. Thereafter, the controller 200 starts a microprogram by a microprogram start means 160.
