Abstract
Address translation circuitry and a method of operating such a translation circuitry are provided. The address translation circuitry is configured to receive a first address used in a first addressing system and to translate it into a second address used in a second addressing system. Translation pipeline circuitry has plural pipeline stages configured to translate the first address into the second address over the course of the plural pipeline stages. Address comparison circuitry is configured to identify an address match condition when a received first address at least partially matches a previously received first address. Insertion circuitry is configured to determine a stage of progress of the previously received first address in the plural pipeline stages and to cause content of the stage of progress of the previously received first address to be unchanged at a next pipeline cycle when the address comparison circuitry identifies the address match condition.
