Zusammenfassung:The embodiment of the invention provides a cache access method and equipment and a processor. The method includes the steps that when first cache equipment confirms that a cache fails according to a first virtual address, the first cache equipment acquires bits, different from indexes of a second virtual address, in indexes of the first virtual address as a first page of coloring bits; a cache failure request is sent to second cache equipment, wherein the cache failure request comprises a first physical address and the first page of coloring bits, first data sent by the second cache equipment according to the cache failure request is received, data and identification corresponding to the indexes of the first virtual address are updated, therefore, it is guaranteed that access to latest data corresponding to the first physical address can be achieved according to the first virtual address, and the data access success rate is increased. 本发明实施例提供种缓存访问方法、设备和处理器,此方法包括:通过当第缓存设备根据第虚拟地址确定缓存失效时,第缓存设备获取第虚拟地址的索引中与第二虚拟地址
