    • A memory management system and method include and use a cache buffer (such as a table look-aside buffer, TLB), a memory mapping table, a scratchpad cache, and a memory controller. The cache buffer is configured to store a plurality of data structures. The memory mapping table is configured to store a plurality of addresses of the data structures. The scratchpad cache is configured to store the base address of the data structures. The memory controller is configured to control reading and writing in the cache buffer and the scratchpad cache. The components are operable together under control of the memory controller to facilitate effective searching of the data structures in the memory management system.
    • 存储器管理系统和方法包括并使用高速缓冲存储器(例如,表查看缓冲器,TLB),存储器映射表,暂存器缓存和存储器控制器。 高速缓存缓冲器被配置为存储多个数据结构。 存储器映射表被配置为存储数据结构的多个地址。 暂存器缓存被配置为存储数据结构的基址。 存储器控制器被配置为控制高速缓冲存储器和暂存器缓存中的读写。 这些组件在存储器控制器的控制下一起可操作,以便有效地搜索存储器管理系统中的数据结构。
