Abstract
PURPOSE: To perform automatically the memory dump of a slave processing unit by the dump indication of a master processing unit which is arranged remotely, by connecting the master information processing unit and the slave information processing unit by a coupler.
CONSTITUTION: When master processing unit 2-1 indicates the start address of an area, which is subjected to memory dump, and the transfer byte length after reading the state of coupler 3-1 and slave information processing unit 1 by a sense command, coupler 3-1 holds this information and stops slave information processing unit 1 and reads DMA data from memory 8 and transfers this data to master information processing unit 2-1.
