Abstract: A multilevel cache-based data read/write method and a computer system. The method includes acquiring a query address of a physical memory data block in which data is to be read/written, acquiring a cache location attribute of the physical memory data block, querying whether a cache is hit until one cache is hit or all caches are missed, where the querying is performed according to the query address in descending order of levels of caches storable for the physical memory data block, and the levels of the caches are indicated by the cache location attribute, and if one cache is hit, reading/writing the data in the query address of the physical memory data block in the hit cache; or, if all caches are missed, reading/writing the data in the query address of the physical memory data block in a memory.

Abstract translation: 基于多级缓存的数据读/写方法和计算机系统。 该方法包括获取要读/写数据的物理存储器数据块的查询地址，获取物理存储器数据块的高速缓存位置属性，查询高速缓存是否被命中，直到一个高速缓存被命中或者所有高速缓存是 错过，按照存储在物理存储器数据块的高速缓存的级别按照查询地址执行查询，并且高速缓存的级别由高速缓存位置属性指示，并且如果一个高速缓存被命中，则读/ 将数据写入命中高速缓存中的物理存储器数据块的查询地址; 或者如果所有高速缓存都被遗漏，则在存储器中的物理存储器数据块的查询地址中读/写数据。
