PURPOSE:To decrease the transfer time of a data, by satisfying the transfer starting conditions synchronously with the synchronizing signal of a system when the data is previously produced at a front-stage buffer and the fact that the interpolation of an interpolating device completes within a period of the system. CONSTITUTION:A differentiating device 8 is added to the conventional constitution, and a signal C5 produced from the device 8 is used for the control signal of a transfer starting device 3. The signal C5 is produced earlier by a period T of a system than an interpolation end signal C3 of an interpolating device 7. Thus an end of the interpolation is previously announced. The data is transferred to a rear-stage buffer 4 from a front-stage buffer 1 by a transfer device 2 with use of the transfer starting signal. Then the signal C5 is applied in place of the signal C3 in the form of the transfer starting conditions. Thus the device 8 is attached, and the waste time of the data transfer is decreased by the output signal of the device 8. As a result, a consecutive working is possible with no discontinuation at a joint of the command data. |
