Zusammenfassung:An apparatus comprises address translation circuitry (70) to perform a translation of a virtual address (80) comprising a virtual tag portion (88) and a virtual address portion (86) into a physical address (82) comprising a physical tag portion (92) and a physical address portion (90). The address translation circuitry comprises address tag translation circuitry (72) to perform a translation of the virtual tag portion into the physical tag portion and the address translation to be performed is selected in dependence on the virtual address. 一种包括地址转换电路(70)的装置，该地址转换电路(70)用于执行虚拟地址(80)到物理地址(82)的转换，该虚拟地址(80)包括虚拟标签部分(88)和虚拟地址部分(86)，该物理地址(82)包括物理标签部分(92)和物理地址部分(90)。地址转换电路包括地址标签转换电路(72)，该地址标签转换电路(72)用于执行该虚拟标签部分到该物理标签部分的转换，并且要执行的该地址转换是根据虚拟地址而选择的。
