Processing system implementing multiple page size memory organization with multiple translation lookaside buffers having differing characteristics
Abstract:
A processing system includes memory management software responsive to a translation lookaside buffer miss. The memory management software updates translation lookaside buffer information based on one or more missed virtual addresses. Entries of a first translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a first criterion. Entries of a second translation lookaside buffer are updated by the memory management software with information corresponding to the missed virtual addresses if memory page size information for the missed virtual addresses meet a second criterion. The first and second criterion may correspond to first and second memory page sizes supported by the respective translation lookaside buffers.
Abstract(Chinese):

处理系统包括响应于翻译后备缓存器未命中的存储器管理软件。 存储器管理软件基于一个或多个错过的虚拟地址更新翻译后备缓冲器信息。 如果缺失的虚拟地址的存储器页面大小信息满足第一准则，则由存储器管理软件更新与虚拟虚拟地址相对应的信息的第一翻译后备缓冲器的条目。 如果缺失的虚拟地址的存储器页面尺寸信息满足第二准则，则由存储器管理软件更新与错过的虚拟地址相对应的信息的第二翻译后备缓冲器的条目。 第一和第二标准可以对应于由相应的翻译后备缓冲器支持的第一和第二存储器页面大小。
