METHOD AND DEVICE FOR CALCULATING DATA RECEIVING TIMING OF ARITHMETIC UNITS, SYNCHRONIZATION METHOD AND DEVICE FOR SYNCHRONIZING PHASES OF THE ARITHMETIC UNITS

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for calculating data receiving timings of a plurality of arithmetic units with high accuracy.;SOLUTION: In the method for calculating data receiving timings of a plurality of arithmetic units for mutually transmitting data to the plurality of arithmetic units, receiving timings of the data to each of the plurality of arithmetic units are calculated. One of the arithmetic units is defined as a transmitter, and other arithmetic units are defined as receivers, The data with sequential numbers are transmitted from the transmitter to the receivers. Each receiver accumulate the data in a buffer memory held inside, reads the sequential numbers successively twice or more from the data accumulated in the buffer memory, calculates the receiving timing of the data from change of the sequential numbers, sequentially changes the arithmetic units to be used as the transmitter at every transmission of the data, and calculates the receiving timing from each transmitter to the receivers.;COPYRIGHT: (C)2011,JPO&INPIT
