PURPOSE:To realize a simple and effective repealing control of a buffer memory and increase the working efficiency of a processor, by installing plural buffer repealing address holding registers plun an address comparator. CONSTITUTION:A store address to a main memory is sent to the corresponding processor in the form of a buffer repealing address in order to secure a coincidence of contents between a main memory and a buffer memory. In this case, plural buffer repealing address holding registers AB1-AB4 plus an address comparator ADC are provided at the sending side of buffer repealing address. Then the store address belonging to the same block is prevented from being held in a plural number in each register AB by the comparator ADC. And the contents of the AB are sent successively to the corresponding to processor in an appropriate period. |
