摘要： One embodiment of the present invention provides a system that facilitates selectively unmarking load-marked cache lines during transactional program execution, wherein load-marked cache lines are monitored during transactional execution to detect interfering accesses from other threads. During operation, the system encounters a release instruction during transactional execution of a block of instructions. In response to the release instruction, the system modifies the state of cache lines, which are specially load-marked to indicate they can be released from monitoring, to account for the release instruction being encountered. In doing so, the system can potentially cause the specially load-marked cache lines to become unmarked. In a variation on this embodiment, upon encountering a commit-and-start-new-transaction instruction, the system modifies load-marked cache lines to account for the commit-and-start-new-transaction instruction being encountered. In doing so, the system causes normally load-marked cache lines to become unmarked, while other specially load-marked cache lines may remain load-marked past the commit-and-start-new-transaction instruction.

摘要： One embodiment of the present invention provides a system for releasing a memory location from transactional program execution. The system operates by executing a sequence of instructions during transactional program execution, wherein memory locations involved in the transactional program execution are monitored to detect interfering accesses from other threads, and wherein changes made during transactional execution are not committed until transactional execution completes without encountering an interfering data access from another thread. Upon encountering a release instruction for a memory location during the transactional program execution, the system modifies state information within the processor to release the memory location from monitoring. The system also executes a commit-and-start-new-transaction instruction, wherein the commit-and-start-new-transaction instruction atomically commits the transaction's stores, thereby removing them from the transaction's write set while the transaction's read set remains unaffected.

摘要： A processor includes a device providing a throttling power output signal. The throttling power output signal is used to determine when to logically throttle the power consumed by the processor. At least one core in the processor includes a pipeline having a decode pipe; and a logical power throttling unit coupled to the device to receive the output signal, and coupled to the decode pipe. Following the logical power throttling unit receiving the power throttling output signal satisfying a predetermined criterion, the logical power throttling unit causes the decode pipe to reduce an average number of instructions decoded per processor cycle without physically changing the processor cycle or any processor supply voltages.

摘要： One embodiment of the present invention supports execution of a start transactional execution (STE) instruction, which marks the beginning of a block of instructions to be executed transactionally. Upon encountering the STE instruction during execution of a program, the system commences transactional execution of the block of instructions following the STE instruction. Changes made during this transactional execution are not committed to the architectural state of the processor until the transactional execution successfully completes.

摘要： Mechanisms have been developed for providing great flexibility in processor instruction handling, sequencing and execution. In particular, it has been discovered that a programmable pre-decode mechanism can be employed to alter the behavior of a processor. For example, pre-decode hints for sequencing, synchronization or speculation control may altered or mappings of ISA instructions to native instructions or operation sequences may be altered. Such techniques may be employed to adapt a processor implementation (in the field) to varying memory models, implementations or interfaces or to varying memory latencies or timing characteristics. Similarly, such techniques may be employed to adapt a processor implementation to correspond to an extended/adapted instruction set architecture. In some realizations, instruction pre-decode functionality may be adapted at processor run-time to handle or mitigate a timing, concurrency or speculation issue. In some realizations, operation of pre-decode may be reprogrammed post-manufacture, at (or about) initialization, or at run-time.
