摘要： A system and method for identifying a TLB entry having a physical address that is within a specified range are disclosed. The method includes obtaining a tentative TLB entry from a page table entry and accessing a physical address associated with the tentative TLB entry. The method further includes comparing the physical address of the tentative TLB entry with a predetermined range of addresses. If the physical address is within the finite range of addresses, an exception is invoked. In response to the exception, the physical address and/or an attribute of the tentative TLB entry can be modified. The tentative TLB entry can then be stored in a TLB.

摘要： Method and system for supporting speculative modification in a data cache are provided and described. In one embodiment, a speculative cache buffer includes a plurality of cache lines and a plurality of state indicators. At least one of the cache lines is operable to receive an evicted cache line from a cache. The at least one of the cache lines is operable to return the evicted cache line to the cache if the cache requests the evicted cache line. Further, the plurality of state indicators is operable to indicate a state of a corresponding cache line of the cache lines.

摘要： Method and system for supporting speculative modification in a data cache are provided and described. A data cache comprises a plurality of cache lines. Each cache line includes a state indicator for indicating anyone of a plurality of states, wherein the plurality of states includes a speculative state to enable keeping track of speculative modification to data in the respective cache line. The speculative state enables a speculative modification to the data in the respective cache line to be made permanent in response to a first operation performed upon reaching a particular instruction boundary during speculative execution of instructions. Further, the speculative state enables the speculative modification to the data in the respective cache line to be undone in response to a second operation performed upon failing to reach the particular instruction boundary during speculative execution of instructions.
