COMMAND SERIALIZATION METHOD AND DEVICE IN INTER-MODULE COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To suppress the deterioration of a transfer rate to the minimum, and to prevent the issue order and processing order of commands from being made different in a system where a plurality of modules are connected like a ring.;SOLUTION: The module serving as a master module is provided with a means for showing the number of command transactions existing in a ring, a means for limiting the issue of the command transactions to the ring and a means for determining whether or not the issue of the command transactions should be limited. When it is determined that the issue of the command transactions should be limited, the issue of the command transactions is limited so that the command transactions can be turned into only command transaction in the ring.;COPYRIGHT: (C)2006,JPO&NCIPI
