Abstract
PURPOSE: To increase the performance of the data processor, by providing the acces bit to the managing table of the buffer memory and taking an advance the block having the greater possibility to be accessed in future in the buffer memory.
CONSTITUTION: The access bit read out from the access managing section 2 is checked. If the value is in logical 0, it is shown that the corresponding block is a block taken in advance before and the presence of first access is possible. Then, the adjacent block having greater possibility to be accessed in future should be taken in advance. Thus, after the access bit of the corresponding block is rewritten in the logic 1 with the data given with the bus 800-1, the output of the selector 500 is given to the adder 700 with the bus 500-1, and the result of addition by the block length is fetched from the bus 700-1 to the auxiliary address register 400. Further, the managing table 200 is checked with the auxiliary address.
