Abstract

PURPOSE:To perform high-frequency INQ processing with efficiency by performing the command chaining of transmission processing and reception processing between two processors and by directly transferring data between the process data areas of both the processors. CONSTITUTION:A request for processing is sent from the 1st process 4-1 in either one of processors 1-1 and 1-2 coupled mutually by an inter-processor coupler 3 through channel devices 2-1 and 2-2, and the result of the processing is returned to the 1st process 4-1. In this state, the command chaining of transmission processing and reception processing between both the processor is performed. Data to be transferred between the 1st and 2nd processes 4-1 and 4-2 are transferred from the data area of one process to that of the other directly without being passed through a buffer.
