Abstract
PURPOSE:To effectively use the memory space of a main processor with an address space occupied by a shared memory by making effective or ineffective the access for the shared memory in accordance with the necessity of a main processor. CONSTITUTION:The system is provided with a first setting means to make an access from a main processor 100 to shared memories 200,201...20n into an effective or ineffective condition and a second setting means to change the setting condition set by the first setting means into the effective or ineffective condition. When the main processor 100 needs to communicate with slave processors 210-21n by means of the shared memories 200,201...20n, the condition set by the first setting means is made into the access effective condition by the second setting means and when communication is not necessary, the condition is made into the access ineffective condition. Consequently, when the communication is not necessary, the shared memory can be occupied in a main memory 102 of the main processor 100 as the access ineffective condition.
