摘要： Generally, this disclosure provides systems, devices, methods and computer readable media for detection and exploitation of lock elision opportunities with binary translation based processors. The device may include a dynamic binary translation (DBT) module to translate a region of code from a first instruction set architecture (ISA) to translated code in a second ISA and to detect and elide a lock associated with a critical section of the region of code. The device may also include a processor to speculatively execute the translated code in the critical section. The device may further include a transactional support processor to detect a memory access conflict associated with the lock and/or critical section during the speculative execution, roll back the speculative execution in response to the detection, and commit the speculative execution in the absence of the detection.

摘要： A checkpoint technique associated with an out of order based architecture of a processing device is described. An instruction may be received by its retirement unit and an identification as to whether the instruction is associated with a speculative error is performed. If the instruction is associated with the speculative error, then a first operation may be performed to replace state values of a first checkpoint of the processing device with state values of a second checkpoint. If the instruction is not associated with the speculative error, then the second checkpoint state may be updated based on the instruction.

摘要： Generally, this disclosure provides systems, methods and computer readable media for binary translation (BT) reuse. The system may include a (BT) module to translate a region of code from a first instruction set architecture (ISA) to a second ISA, for execution associated with a first process. The BT module may also be configured to store a first physical page number associated with the translated code and the first process. The system may also include a processor to execute the translated code and to update a virtual address instruction pointer associated with the execution. The system may further include a translation reuse module to validate the translated code for reuse by a second process. The validation may include generating a second physical page number based on a page table mapping of the updated virtual address instruction pointer and matching the second physical page number to the stored first physical page number.

摘要： A processor includes a binary translator, a memory management unit, and a monitor unit. The binary translator includes logic to translate a region of code and to reorder translated instructions within the region to produce a transaction. The memory management unit includes logic to receive a memory instruction from the transaction to access an address in memory, determine whether the address is associated with a previous page table walk during execution of the transaction based on bits set for addresses during the previous page table walk, and allow execution of the memory instruction based upon the determination whether the address is associated with the previous page table walk. The monitor unit includes logic to specify whether a given address is associated with the previous page table walk during execution of the transaction.
