Abstract
PURPOSE: To enable the priority processing of data without providing the priority buffer, by storing the data of priority processing to the buffer after the end of processing for the buffer during readout, in the cyclic data processing of multi- stage buffer.
CONSTITUTION: The buffers M1 to MN of N-stage and the buffer counters A and B to control the cyclic operation are provided. The counter A indicates the number 9 of the buffer M to store the data of one unit formed from the data forming circuit K, the counter B indicates the number b of the buffer M read out from the data processing circuit P, and the numbers a and b are compared with each other at the comparison circuit C. When the data for emergency processing is taken place, the circuit K stores the data for emergency processing to the buffer when the circuit P is finished for processing for the data from the buffer during readout processing at present. The counter B makes the number b to -1, the buffer is again read out, the emergency data is processed with priority by the circuit P.
