Abstract
PURPOSE: To detect the error due to the overflow of stack memory easily, by providing the detection means to detect the specific value represented in the stack counter, in the data processor having the stack area indicating the address shunt.
CONSTITUTION: The stack exclusive memory 1 having the shunt address permissible addresses of n sets writes in the shunt addresses A1WAi (where: i is the number of times of subroutine processing generation), when the interruption processing and subroutine processing are caused, by the number of times of production, and the counter 4 counts the number of times i. The number of times i is interpreted with the decoder 6 and when i=n+1, the detection signal B is produced. The logical judgement between the signal B and the interruption control signal A is made at the logic circuit 8 to produce the internal interruption signal with the internal interruption control circuit 9. Further, in case of the interruption shunt addresses IWK address from external, i=K is detected with the decoder 6 and the signal C is produced when the interruption from external is no more received, and it is fed to the external interruption control circuit 7.
