摘要： Managing speculative execution via groups of actions corresponding to atomic traces enables efficient processing of flag-related actions, as atomic traces advantageously enable single checkpoints of flags at trace boundaries. Flag restoration from checkpoints for trace aborts uses a flag checkpoint table to store flag checkpoints, each corresponding to an atomic trace. The table is accessed for flag restoration in response to a trace abort. In a first technique, a corresponding flag checkpoint is stored in response to trace renaming, and the flag checkpoints are updated as flags are modified. Flags are restored from the flag checkpoint corresponding to an aborted atomic trace. In a second technique, a corresponding flag checkpoint is allocated to an invalid state in response to trace renaming, and initialized on-demand when flags are first modified in accordance with the atomic trace. Flags are restored from the oldest flag checkpoint starting from an aborted atomic trace.

摘要： Prediction of data values to be read from memory by a microprocessor for load operations. In one aspect, a method for predicting a data value that will result from a load operation to be executed by the microprocessor includes accessing an entry in a load value prediction table that stores a predicted data value corresponding to the load operation. The predicted data value is stored in a physical storage destination of the microprocessor to be available as a result of the load operation without waiting for execution of the load operation to complete. The storage destination is the destination for a loaded data value resulting from executing the load operation.

摘要： Software hints embedded in branch instructions direct selection of one of a plurality of branch predictors to use when processing the branch instructions, leading to improved branch prediction (i.e. fewer mis-predictions) over conventional schemes. A software agent assembles branch instructions having associated respective branch predictor control fields compatible with a branch predictor selector and a plurality of branch predictors. Each branch predictor control field is used to perform branch predictor selection, branch predictor control, or both. Branch predictor selection enables selective branch prediction according to an appropriate one of the branch predictors as determined by the software agent by examining context surrounding the branch instruction. Branch predictor control enables control of operation of one or more of the branch predictors. For example, a history-based branch predictor may be instructed to provide branch prediction according to a history-depth specified by the branch predictor control.

摘要： Managing speculative execution via groups of one or more actions corresponding to atomic traces enables efficient processing of flag-related actions, as atomic traces advantageously enable single checkpoints of flag values at atomic trace boundaries. Checkpointing flags during atomic trace renaming in a processor system uses a flag checkpoint table to store a plurality of flag checkpoints, each corresponding to an atomic trace. The table is selectively accessed to provide flag information to restore speculative flags when an atomic trace is aborted. A corresponding flag checkpoint is stored when an atomic trace is renamed. An action that updates flags updates all entries in the table corresponding to younger atomic traces. If the atomic trace is aborted, then the corresponding flag checkpoint is used for restoration of flag state.

摘要： A software agent assembles prefetch hint instructions or prefixes defined in an instruction set architecture, the instructions/prefixes conveying prefetch hint information to a processor enabled to execute instructions according to the instruction set architecture. The prefetch hints are directed to control operation of one or more hardware memory prefetcher units included in the processor, providing for increased efficiency in memory prefetching operations. The hints may optionally provide any combination of parameters describing a memory reference traffic pattern to search for, when to begin searching, when to terminate prefetching, and how aggressively to prefetch. Thus the hardware prefetchers are enabled to make improved traffic prediction, providing more accurate results using reduced hardware resources. The hints may include any combination of specific pattern hints (one/two/N-dimensional strides, indirect, and indirect-stride), modifiers including sparse and region, and a prefetch-stop directive. The parameters may include any combination of a count, a priority and a ramp.
摘要翻译：软件代理装配在指令集架构中定义的预取提示指令或前缀，指令/前缀将预取提示信息传送到能够根据指令集架构执行指令的处理器。预取提示旨在控制包括在处理器中的一个或多个硬件存储器预取器单元的操作，从而提高存储器预取操作的效率。提示可以可选地提供描述存储器参考流量模式的参数的任何组合以搜索，何时开始搜索，何时终止预取，以及如何积极地预取。因此，硬件预取器能够进行改进的流量预测，使用减少的硬件资源提供更准确的结果。提示可以包括特定模式提示（一/二/ N维步幅，间接和间接步幅），包括稀疏和区域的修饰符以及预取停止指令的任何组合。这些参数可以包括计数，优先级和斜坡的任何组合。
