<p>PURPOSE:To minimize the deterioration of throughput in case an access has the conflict by providing the random access memories of the same address constitution to the microprocessors respectively. CONSTITUTION:In a data reading mode each microprocessor gives an access individually to a random access memory corresponded respectively and reads out data independently of other microprocessors. When a data writing request is given from a certain microprocessor, the same data are written simultaneously to the same address position of all random access memories respectively. If the writing requests have conflicts, the writing processes are carried out according to the prescribed priority. Thus the physical plural memories function as a single logic shared memory consisting of the same data.</p> |
