Abstract
PURPOSE:To eliminate the time required for indexing of a translation look-aside buffer to improve the performance of an information processing device, by indexing the buffer memory by a virtual address. CONSTITUTION:When directories of translation look-aside buffers 2a and 2b corresponding to the access by the address of virtural page storing register 1b coincide with the page information of virtual page storing register 1a in comparators 4a and 4b, virtual addresses from registers 1a and 1b and register 1c, in which the address in the page is stored, are applied to buffer memory directories 15a... by control part 20, and write data is written to one of buffer memory data storages 9a... at the write request time in accordance with coincidence due to one of comparators 11a.... Data is read similarly at the read request time, and thus, the buffer memory is indexed without converting the virtual address to an actual address, and the time required for indexing of the translation look-aside buffer is eliminated to improve the information processing performance.
