Abstract

PURPOSE: To prevent the increase in the loss time required for repairment and replacement of defective banks and the decrease in the main memory capacity, by making possible to change the content of the constituent control register defining the constitution of the main memory with the instruction from the diagnosis processor.
CONSTITUTION: To the CPU 1, the diagnosis processing unit 2 and the main memory control unit 3 are connected. The main memory control unit 3 is provided with the constitution control register 4, first and second address storage registers 5 and 6, selector 7, and main memory access register 8, to which the main memory unit 9 having the first to fourth banks 10 to 13 is connected. The alteration of interleave is controlled at the diagnosis processing unit 2, and it is made by rewriting the content of the constitution control register with the control information from the diagnosis processing unit.
