<p>PURPOSE:To perform information transfer among plural processors which do not use a memory in common through simple constitution, by executing an instruction group stored in the memory of a global processor at specified intevals of time. CONSTITUTION:In the system wherein local processors 12 and 13 use their own memories 15 and 16 in common with only a global processor 14, instructions A and B for transfer between the processors 12 and 13 are set up in the memory 30 of the processor 14, and are selected by an external clock. Further, a communication area between the processor 12 and 13 is transferred, clock by clock, in predetermined order, and the processors 12 and 13 are inhibited from accessing the communication area between the processors 12 and 13 until the transfer ends, thereby outputting access permit signals from the processors 12 and 13.</p> |
