Abstract
PURPOSE: To increase the processing rate of a multiprocessor system by converting a partial write request into an entire write request without causing a data dissidence between a main memory and buffer memory.
CONSTITUTION: Processor 1, etc., is applied with an address correcponding to a partial write request and when it agrees with the contents of directory ADI1 stored with addresses of buffer memory MB1 of processor 1, the request couples with read data of memory MB1 at the address position and is converted into an entire write request. Further directory AD21 similar to directory ADI1 of controller 3 is compared with directory AD22 similar to directory AD12 of another processor 2 and when their coincidence is detected, the address of directory AD22 is invalidated and when the dissidence to directory AD21 is detected, the converted entire write request is returned, so that the partial write request will be converted into the entire write request high in processing speed without causing dissidence between common main memories 4 and 5 and memories MB1 and MB2.
