摘要：
Various technologies and techniques are disclosed for concurrently performing address translation data lookups for use by an emulator. On a first thread, a first lookup is performed for address translation data for use by an emulator. On a second thread, a second lookup for the address translation data is concurrently and speculatively performed. The address translation data from a successful lookup from either the first lookup or the second lookup is used to map a simulated physical address to a virtual address of the emulator. For example, the first thread can perform a translation lookaside buffer lookup while the second thread concurrently and speculatively performs a page table entry lookup for the address translation data.
