Abstract
A computing device comprises a processor, a table walker, and a memory storing a segmented reverse map table in multiple non-contiguous portions of the memory. The table walker is configured to translate a virtual memory address specified by a memory access request to a physical memory address associated with the virtual memory address; and provide a requester associated with the memory access request with access to the associated physical memory address in response to an indication at the reverse map table that the requester is authorized to access the associated physical memory address.
