Abstract
An address translation mechanism for generating real addresses, within a page. based on stride from a beginning translated address in the page. However, whenever there is a page crossing, an address must go to either the directory look aside table (DLAT) or buffer control element (BCE) to translate a virtual page-address to a real page-address. To avoid the delay this usually causes, the address translation request is sent out before the address is actually needed. This is done by predicting the next page-crossing while real addresses with the current page are being generated based on the stride value. The prediction is based on the stride value, operand size, and page mode.
