Command transfer control method, apparatus, and system

摘要

Buffer means for storing and retaining command data is placed between a command transmission unit for sending command data and a command reception unit for receiving the sent command data and performing processing operation based on the command data, a plurality of command data pieces for controlling processing of the command data are sent in batch from the command transmission unit to the command reception unit, and the command data pieces are temporarily stored and retained in the buffer means so that the command data pieces can be retrieved in order. It is possible to cope with rapid change in the operation and control, and the whole performance of a data transmission and reception system can be maintained.
