Zusammenfassung: | An information handling system and method for translating virtual addresses to real addresses including a processor for processing data; memory devices for storing the data; and a memory controller configured to control accesses to the memory devices, where the processor is configured, in response to a request to translate a first virtual address to a second physical address, to send from the processor to the memory controller a page directory base and a plurality of memory offsets. The memory controller is configured to: read from the memory devices a first level page directory table using the page directory base and a first level memory offset; combine the first level page directory table with a second level memory offset; and read from the memory devices a second level page directory table using the first level page directory table and the second level memory offset. |
