Abstract

PURPOSE:To improve the throughput of a channel, by controlling a channel buffer to be adapted to the property of accessing, through the use of the channel buffer in channel unit or the like with specific discriminating information. CONSTITUTION:When a fetch and access request from a channel 10 comes, a prescribed amount of data to be consecutive including fetched request data is loaded from a main storage device 1 to a channel buffer CHB3. When a storage access request comes from the channel 10, the stored data is once stored in the CHB3 and stored to the main storage device 1 when a prescribed amount of stored data is stored in the CHB3. In such a computor system, the CHB3 is used for the channel 10 or input and output devices with unit split by using discriminating information which can specify the channel 10 or the input and output device unequivocally based on the address referring the CHB3.
