Abstract

PURPOSE:To update buffer memories efficiently by providing each information processor, having the buffer memory, with a main memory indicator which indicates the state of relation with a main memory. CONSTITUTION:Information processors 2 and 2' sharing a main memory 1 and having buffer memories 3 and 3' respectively are provided with main memory indicators 10 and 10' which indicate the shared state of the memory 1 by the devices 2 by region blocks. Therefore, when the memory 3 of the device 2, etc., is to be updated, the shared state of information of the block of the memory 1 to be stored as to the device 2' is found immediately by referring to the indicator 10, thereby eliminating the need to transfer registration information to the device 2' and to process a response, etc., from the device 2' to the device 2. Consequently, the buffer memories are updated efficiently.
