Abstract
PURPOSE: To improve the capacity of an information processor by making a page alignment with a page with a small number of times of access.
CONSTITUTION: In case that associative registers 13 have all been stored, a resistor is substituted with register 13 which was referred to in the oldest time and the contents of memory-access time register 11 equivalent to the substituted register 13 are added to memory-access summing register 9 of the corresponding page via signal line 106. Since the contents of register 9 of each page can be referred to by software via signal line 107 at every time when page ejection is required through the repetitive operation mentioned above, a page of the lowest frequency in memory access among pages can be taken as a page-ejection object, so that the entire capacity will improve.
