Abstract
PURPOSE: To finish write operation through single operation by detecting the generation of a continuous write request for the same access unit of a memory unit and by simultaneously merging the following write request data.
CONSTITUTION: When requests from CPUs 1-1 and 1-2 and CHPs 2-1 and 2-2 as processors are written in main memory units 3-1 and 3-2, requests are stored in port parts 5-1W 5-4 temporarily and various information including this stored access address information and write data is inputted to shift register 9 and held there during an access run. Address information outputted from this register 9 is compared by comparing circuit 20 with access addresses held in port parts 5-1W5-4. When circuit 20 detects the generation of continuous write requests for the same single area of units 3-1 and 3-2, the following write request data are merged by the merging circuit with write processing data before the execution, so that the processing may be completed through the single write operation.
