摘要： Mechanisms, in a data processing system, are provided for tracking effective addresses through a processor pipeline of the data processing system. The mechanisms comprise logic for fetching an instruction from an instruction cache and associating, by an effective address table logic in the data processing system, an entry in an effective address table (EAT) data structure with the fetched instruction. The mechanisms further comprise logic for associating an effective address tag (eatag) with the fetched instruction, the eatag comprising a base eatag that points to the entry in the EAT and an eatag offset. Moreover, the mechanisms comprise logic for processing the instruction through the processor pipeline by processing the eatag.

摘要： A mechanism is provided for thread completion arbitration. The mechanism comprises executing more than two threads of instructions simultaneously in the processor, selecting a first thread from a first subset of threads, in the more than two threads, for completion of execution within the processor, and selecting a second thread from a second subset of threads, in the more than two threads, for completion of execution within the processor. The mechanism further comprises completing execution of the first and second threads by committing results of the execution of the first and second threads to a storage device associated with the processor. At least one of the first subset of threads or the second subset of threads comprise two or more threads from the more than two threads. The first subset of threads and second subset of threads have different threads from one another.

摘要： Mechanisms are provided, in a processor, for executing instructions that are younger than a previously dispatched synchronization (sync) instruction is provided. An instruction sequencer unit of the processor dispatches a sync instruction. The sync instruction is sent to a nest of one or more devices outside of the processor. The instruction sequencer unit dispatches a subsequent instruction after dispatching the sync instruction. The dispatching of the subsequent instruction after dispatching the sync instruction is performed prior to receiving a sync acknowledgement response from the nest. The instruction sequencer unit performs a completion of the subsequent instruction based on whether completion of the subsequent instruction is dependent upon receiving the sync acknowledgement from the nest and completion of the sync instruction.

摘要： Various systems, processes, products, and techniques may be used to manage thread transitions. In particular implementations, a system and process for managing thread transitions may include the ability to determine that a transition is to be made regarding the relative use of two data register sets and determine, based on the transition determination, whether to move thread data in at least one of the data register sets to second-level registers. The system and process may also include the ability to move the thread data from at least one data register set to second-level registers based on the move determination.

摘要： A processor core includes a transactional memory, a transaction failure instruction address register (TFIAR), and a transaction failure data address register (TFDAR). The transactional memory stores information of a plurality of transactions executed by the processor core. The processor core retrieves instruction and data address associated with the aborted transaction from TFIAR and TFDAR respectively and stores them into a profiling table. The processor core then generates profiling information based on instruction and data addresses associated with the aborted transaction.
