摘要： A method and apparatus for providing efficient strong atomicity is herein described. Optimized strong operations may be inserted at non-transactional read accesses to provide efficient strong atomicity. A global transaction value is copied at a beginning of a non-transactional function to a local transaction value; essentially creating a local timestamp of the global transaction value. At a non-transactional memory access within the function, a counter value or version value is compared to the LTV to see if a transaction has started updating memory locations, or specifically the memory location accessed. If memory locations have not been updated by a transaction, execution is accelerated by avoiding a full set of slowpath strong atomic operations to ensure validity of data accessed. In contrast, the slowpath operations may be executed to resolve contention between a transactional and non-transaction access contending for the same memory location.
摘要翻译：这里描述了提供有效的强原子性的方法和装置。可以在非事务性读访问中插入优化的强操作，以提供有效的强原子性。全局事务值在非事务函数的开头被复制到本地事务值; 基本上创建了全局事务值的本地时间戳。在功能内的非事务性存储器访问中，将计数器值或版本值与LTV进行比较，以查看事务是否开始更新存储器位置，或具体地访问存储器位置。如果事务没有更新存储器位置，则通过避免一整套的慢路强原子操作来加速执行，以确保访问的数据的有效性。相比之下，可以执行慢路操作来解决争用相同内存位置的事务和非事务访问之间的争用。

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。

摘要： A method and apparatus for providing efficient strong atomicity is herein described. Optimized strong operations may be inserted at non-transactional read accesses to provide efficient strong atomicity. A global transaction value is copied at a beginning of a non-transational function to a local transaction value; essentially creating a local timestamp of the global transaction value. At a non-transactional memory access within the function, a counter value or version value is compared to the LTV to see if a transaction has started updating memory locations, or specifically the memory location accessed. If memory locations have not been updated by a transaction, execution is accelerated by avoiding a full set of slowpath strong atomic operations to ensure validity of data accessed.

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.
