Abstract

PURPOSE: To transfer the information at a high speed by setting the flag information showing the presence of write every time an information signal is written into a prescribed address of a transfer memory and granting the read based on the flag information.
CONSTITUTION: An information signal is written into a prescribed address of a transfer memory 200 via a 1st device 100 and then read out of the memory 200 via a 2nd device 300. A storage means 400 stores the flag information showing the presence/absence of write of the information signal in accordance with the address of the memory 200. A flag information write means 500 sets the flag information on an address of the means 400 where the information is written to the presence of write in accordance with the write of the device 100. At the same time, the flag information on an address of the means 400 where the information is read out is set to the absence of write in accordance with the read of the device 300. A read grant means 600 grants the read of only the information signal to which the flag information on the means 400 shows the presence of write to the memory 200.
