Abstract

PURPOSE: To avoid the useless channel transfer by prefetching the number of the transfer words sent from the processor of the remote side by the device of the receiving system and then realizing the security of the necessary data reception storing area as well as the disignation of the number of the received words.
CONSTITUTION: When the transmission start request signal WRIT START is turned on by the processor of transmission system, the initialization is given to the counter 12 through the gate 22 when the FF14 is off, i.g. the buffer register 10 is idle. And the data are stored successively into the register 10 by the data transfer signal WRIT STB, and then the end interruption is given by the transmission end signal SEND TERM. On the other hand, if the reception start request signal READ START is supplied to the gate during the reception, the data word number stored in the register 10 is prefetched through the gates 18 and 16 when the FF14 is on. And the processor of reception system takes in the reception signal READ STB by the number equivalent of the word number. Thus the useless channel transfer can be avoided by the word number prefetching control of the effective data to be received.
