摘要： Hardware checkpoints may be used to mark software-based speculation regions. An instruction may be provided at the beginning of a speculation region and at the end of the speculation region. If an exception occurs during the speculation region, a hardware rollback may be occurred. The hardware rollback rolls back to the instruction at the beginning of the speculation region. The hardware may take a checkpoint by taking a register snapshot and treating future memory updates as tentative. When the instruction marking the end of the speculation is reached, all the tentative memory updates are committed and the previously taken register snapshot is discarded.

摘要： A processor core includes a processor to execute a first translated instruction translated from a first instruction stored in first page of a memory. The processor also includes a translation indicator agent (XTBA) to store a first translation indicator that is read from a physical map (PhysMap) in the memory. In an embodiment, the first translation indicator is to indicate whether the first page has been modified after the first instruction is translated. Other embodiments are described as claimed.

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： A processor includes an allocator with logic assigning alias hardware resources to instructions within an atomic region of instructions. The atomic region includes reordered instructions.

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.
