摘要：In a multiprocessor system having a plurality of processors connected througha bus, upon requesting message passing, a processor notifies, the request to otherprocessors by designating identifiers of candidate destination processors from a register5, an upper limit in a register UNR 8 and a lower limit in a register LNR 7. These provide a
range for the number of destination processors required. A counter 9 countsacknowledge signals from candidate destination processors ready for messagereception. A comparator 10 compares the count value with the lower and higher limitvalues in registers 7 and 8. If the count value is not less than the lower limit value, thesending processor determine that it can perform message passing. If the count value istreater than the upper limit value, the processor selects as many processors as the upperlimit number from the candidate destination processors according to a rule based onpriority, and then initiates the message passing to the processor thus selected.
