Abstract

PURPOSE: To enable the debugging at the same environment as the ON-line system processing even with the ON-line computer in operation, by constituting the multi computer system providing the computer exclusive use for debugging.
CONSTITUTION: The areas of the global memories 1, 2 are used by separating them for ON-line processing 1 and debug. the ON-line CPU 3 and debug CPU respectively perform the formation of program and debug. The multiplex access control set 5 has the processor selection and selector switch function, and if failure is taken place to the ON-line magnetic drum 6, debug is interrupted and the debug magnetic drum 7 is selected for ON-line. The common input and output unit control set 8 is to commonly use the low speed input and output unit between processors, and the selector control is made by program. With this constitution, even if the on-line CPU is under processing, the debug is possible with the same condition as the on- line processing with the debug CPU.
