摘要： A method and apparatus for efficiently executing nested transactions is herein described. Hardware support for execution of transactions is provided. Additionally, through the use of logging previous values immediately before a current nested transaction in a local memory and storage of a stack of handlers associated with a hierarchy of transactions, nested transactions are potentially efficiently executed. Upon a failure, abort, or invalidating event/access within a nested transaction, the state of variables or memory locations written to during execution of the nested transaction are rolled-back to immediately before the nested transaction, instead of all the way back to an original state of the variables or memory locations before an enclosing transaction. As a result, nested transactions may be re-executed within enclosing transactions, without flattening the enclosing and nested transactions to re-execute everything.
摘要翻译：这里描述用于有效执行嵌套事务的方法和装置。提供了执行交易的硬件支持。另外，通过在本地存储器中的当前嵌套事务之前使用先前的值记录以及与事务层次结构相关联的处理程序堆栈的存储，可以有效地执行嵌套事务。在嵌套事务中出现故障，中止或无效事件/访问时，在嵌套事务执行期间写入的变量或内存位置的状态将回滚到嵌套事务之前，而不是一直返回到包含事务之前的变量或内存位置的原始状态。因此，嵌套事务可能会在封闭事务中重新执行，而不会使包围和嵌套事务变扁，以重新执行所有事务。

摘要： A method and apparatus for providing optimized strong atomicity operations for non-transactional writes is herein described. Locks are acquired upon initial non-transactional writes to memory locations. The locks are maintained until an event is detected resulting in the release of the locks. As a result, in the intermediary period between acquiring and releasing the locks, any subsequent writes to memory locations that are locked are accelerated through non-execution of lock acquire operations.

摘要： A method and apparatus for ensuring integrity of transaction exit functions is herein described. Dead local data in a transaction is prevented from overwriting local variables associated with a transaction exit function. In a write-buffering Software Transactional Memory (STM) system, a commit function is associated with a private stack to store local variables to ensure write-back of local dead data in a write-buffer does not corrupt the commit function. Similarly, in a roll-back STM, an abort function is associated with a private stack to store local variables to ensure the roll-back of a program stack with local dead data from a write log does not corrupt the abort function. Alternatively, one stack may be used for the transaction including a first function and an exit function. Here, local dead variables are detected and prevented from overwriting local variables of the exit function.

摘要： In accordance with some embodiments, software transactional memory may be used for both managed and unmanaged environments. If a cache line is resident in a cache and this is not the first time that the cache line has been read since the last write, then the data may be read directly from the cache line, improving performance. Otherwise, a normal read may be utilized to read the information. Similarly, write performance can be accelerated in some instances to improve performance.
摘要翻译：根据一些实施例，软件事务存储器可以用于被管理的和非管理的环境。如果高速缓存行驻留在缓存中，并且这不是自上次写入以来第一次读取高速缓存行，则可以直接从高速缓存行读取数据，从而提高性能。否则，可以使用正常读取来读取信息。同样，在某些情况下，写入性能可以加快，以提高性能。
