A mapping processing method and apparatus for a cache address, where the method includes acquiring a physical address corresponding to an access address sent by a processing core, where the physical address includes a physical page number (PPN) and a page offset, mapping the physical address to a Cache address, where the Cache address includes a Cache set index 1, a Cache tag, a Cache set index 2, and a Cache block offset in sequence, where the Cache set index 1 with a high-order bit and the Cache set index 2 with a low-order bit together form a Cache set index, and the Cache set index 1 falls within a range of the PPN. Some bits of a PPN of a huge page PPN are mapped to a set index of a Cache so that the bits can be colored by an operating system.
