TIME POINT SYNCHRONIZING SYSTEM

摘要

PURPOSE:To set plural information processors at the same time point by always transmitting the time point data and the periodic pulses to a time point timer of each information processor from a reference time point device. CONSTITUTION:A processor 2 contains a time point timer 21, a serial/parallel converter 22 and an adder 23 which form a time point timer control part. A reference time point device 1 is connected to the time point timer control part of the processor 2 via the interface lines 101 (DATA), 102 (STROB), 103 (1S PULSE) and 104 (1MS PULSE). The higher rank parts (H, M and S) of the timer 21 serve as the registers which store the time point data together with a lower rank part (MS) serving as a counter containing a counting function respectively. The device 1 always transmits the DATA, STROB and 1S PULSE signals via an interface and the processor 2 fetches the time point data via the interface and in response to those signals.
