<p>PROBLEM TO BE SOLVED: To efficiently perform data exchange between two pairs of processors by arranging input data to processors so that data exchange can be performed from the direction where communication lines do not overlap and performing transfer control so that arranged data may be performed data exchange by the same operation means from mutually different directions. SOLUTION: The communication path between processors PE0 and PE15 does not compete with the communication path between processors PE7 and PE8, and the communication path between processors PE1 and PE14 does not compete with the communication path between processors PE6 and PE9. Similarly, the communication path between processors PE2 and PE13 does not compete with the communication path between processors PE5 and PE10, and the communication path between processors PE3 and PE12 does not compete with the communication path between processors PE4 and PE11. With this, the data exchange between the processors PE0 and PE15 and the data exchange between the processors PE7 and PE8 are simultaneously carried out. The same thing is true of the other processors. This improves data exchange efficiency.</p> |
