    • A method and apparatus for efficient and consistent validation/conflict detection in a Software Transactional Memory (STM) system is herein described. A version check barrier is inserted after a load to compare versions of loaded values before and after the load. In addition, a global timestamp (GTS) is utilized to track a latest committed transaction. Each transaction is associated with a local timestamp (LTS) initialized to the GTS value at the start of a transaction. As a transaction commits it updates the GTS to a new value and sets versions of modified locations to the new value. Pending transactions compare versions determined in read barriers to their LTS. If the version is greater than their LTS indicating another transaction has committed after the pending transaction started and initialized the LTS, then the pending transaction validates its read set to maintain efficient and consistent transactional execution.
    • 这里描述了用于在软件事务存储器(STM)系统中有效且一致的验证/冲突检测的方法和装置。 在加载之后插入版本检查障碍,以便在加载之前和之后比较加载值的版本。 此外,使用全局时间戳(GTS)来跟踪最近提交的事务。 每个事务与在事务开始时初始化为GTS值的本地时间戳(LTS)相关联。 作为事务提交,将GTS更新为新值,并将修改的位置的版本设置为新值。 待处理的交易将比较其在LTS阅读障碍中确定的版本。 如果版本大于其LTS,指示在挂起事务启动并初始化LTS之后另一个事务已经提交,则挂起的事务会验证其读取集合以保持有效且一致的事务执行。

    • A dual-band mobile communication device includes a ground plane and an antenna located on a dielectric substrate and including a feeding portion and a shorted radiating portion. One end of the feeding portion is a feeding point of the antenna. A length of the shorted radiating portion is at least twice that of the feeding portion. A first end of the shorted radiating portion, electrically connected to the ground plane, is a shorting end, and the second end of the shorted radiating portion is an open end. The shorted radiating portion includes multiple bendings which form multiple fractional sections. The open end of the shorted radiating portion extends toward a first fractional section of the shorting end of the shorted radiating portion. A coupling gap exists between a second fractional section of the open end of the shorted radiating portion and the feeding portion.
