<p>PURPOSE:To easily and inexpensively constitute a microcomputer appropriate to a multiprocessor system for transferring data between processors through a memory. CONSTITUTION:The microcomputer 100 having an internal memory 120 is provided with a bus control part 130 connecting between external buses and internal buses so that another external microcomputer 150 can access the internal memory 120 from the external buses through the internal buses when both internal buses 101, 102 are unused at the time of generating an access request from the microcomputer 150 to the memory 120.</p> |
