Abstract
Addresses of all of dirty blocks of a cache memory are, by an update address registering section, stored in one of plural regions of an update address memory. When a certain cache block is brought to a dirty state and then suspended from the dirty state, the update address removing section removes the address from the region. When cache flush is performed, a flush executing section sequentially fetches the addresses of the dirty blocks from each region to issue, to the system bus, a command for writing-back data indicated by the address into the main memory so that the contents of all of the a dirty block are written-back into the main memory. Therefore, the cache flush apparatus according to the present invention is able to shorten time required to perform the cache flush procedure and to improve the performance of a computer system having the cache flush apparatus.
