Abstract

PURPOSE: To control effectively a multistage buffer by using a needed and irreducible number of logic circuits.
CONSTITUTION: Counter 11 is provided which decides on the order of data service factors and service factor memory flags 14 and 15 which correspond to data buffers are set by the counter 11 at every time when each service factor is generated, so that when even either data service factor memory flag 14 or 15 is set, a corresponding service will be started. In addition, this system is provided with a flag for a stand-by in case that the service is in process at that time. Then, counter 21 makes a decision on a buffer to and from which data in process of the service are inputted and outputted, and determines whether the data service factor memory flag should be reset at the time of a operation end, thereby controlling several stages of data buffer in regular order. Further, even if a next service factor is generated before the service operation end, the error is detected.
