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： One embodiment of the present invention provides a system that supports executing a fail instruction, which terminates transactional execution of a block of instructions. During operation, the system facilitates transactional execution of a block of instructions within a program, wherein changes made during the transactional execution are not committed to the architectural state of the processor until the transactional execution successfully completes. If a fail instruction is encountered during this transactional execution, the system terminates the transactional execution without committing results of the transactional execution to the architectural state of the processor.

摘要： A technique for operating a computing apparatus includes allocating a working register file entry corresponding to a register in a working register file when an instruction referencing the register proceeds through a particular stage of the computing apparatus. The technique maintains the working register file entry until at least a predetermined number of subsequent instructions have similarly proceeded through the particular stage.

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.

摘要： One embodiment of the present invention provides a system that facilitates storing results of resolvable branches during speculative execution, and then using the results to predict the same branches during non-speculative execution. During operation, the system executes code within a processor. Upon encountering a stall condition, the system speculatively executes the code from the point of the stall, without committing results of the speculative execution to the architectural state of the processor. Upon encountering a branch instruction that is resolved during speculative execution, the system stores the result of the resolved branch in a branch queue, so that the result can be subsequently used to predict the branch during non-speculative execution.

摘要： One embodiment of the present invention provides a system that facilitates avoiding locks by speculatively executing critical sections of code. During operation, the system allows a process to speculatively execute a critical section of code within a program without first acquiring a lock associated with the critical section. If the process subsequently completes the critical section without encountering an interfering data access from another process, the system commits changes made during the speculative execution, and resumes normal non-speculative execution of the program past the critical section. Otherwise, if an interfering data access from another process is encountered during execution of the critical section, the system discards changes made during the speculative execution, and attempts to re-execute the critical section.
