Abstract
In one embodiment, a microprocessor, comprising: a translation lookaside buffer (TLB) configured to indicate that a virtual page address corresponding to a physical page address of a page of memory that a memory access instruction is attempting to access is missing in the TLB; a first micro-op corresponding to a first memory access instruction and configured to initiate a first speculative tablewalk based on a miss in the TLB of a first virtual page address; and a second micro-op corresponding to a second memory access instruction, the second micro-op configured to take over an active first speculative tablewalk of the first micro-op at its current stage of processing based on being older than the first micro-op and further based on having a virtual page address and properties that match the first virtual page address and properties for the first memory access instruction.
