摘要： An apparatus and method is described herein for conditionally committing and/or speculative checkpointing transactions, which potentially results in dynamic resizing of transactions. During dynamic optimization of binary code, transactions are inserted to provide memory ordering safeguards, which enables a dynamic optimizer to more aggressively optimize code. And the conditional commit enables efficient execution of the dynamic optimization code, while attempting to prevent transactions from running out of hardware resources. While the speculative checkpoints enable quick and efficient recovery upon abort of a transaction. Processor hardware is adapted to support dynamic resizing of the transactions, such as including decoders that recognize a conditional commit instruction, a speculative checkpoint instruction, or both. And processor hardware is further adapted to perform operations to support conditional commit or speculative checkpointing in response to decoding such instructions.

摘要： An apparatus and method is described herein for coupling a processor core of a first type with a co-designed core of a second type. Execution of program code on the first core is monitored and hot sections of the program code are identified. Those hot sections are optimize for execution on the co-designed core, such that upon subsequently encountering those hot sections, the optimized hot sections are executed on the co-designed core. When the co-designed core is executing optimized hot code, the first processor core may be in a low-power state to save power or executing other code in parallel. Furthermore, multiple threads of cold code may be pipelined on the first core, while multiple threads of hot code are pipeline on the co-designed core to achieve maximum performance.

摘要： Dynamically switching cores on a heterogeneous multi-core processing system may be performed by executing program code on a first processing core. Power up of a second processing core may be signaled. A first performance metric of the first processing core executing the program code may be collected. When the first performance metric is better than a previously determined core performance metric, power down of the second processing core may be signaled and execution of the program code may be continued on the first processing core. When the first performance metric is not better than the previously determined core performance metric, execution of the program code may be switched from the first processing core to the second processing core.
