| 摘 要： | 本文分析了目前提出的硬件事务内存系统在支持线程切换及迁移、内存页置换、系统调用等方面存在的问题,并提出了新的支持操作系统的实现方案DTM。DTM采用单独的面向事务处理的一致性协议来检测及仲裁事务间冲突,与传统的事务内存系统相比,DTM具有实现简单、可扩展性好及性能上的优势。

| Abstract: | This paper summarizes the problems for the currently proposed hardware transactional memory system which supports context switch/migration,virtual memory paging,and system call issues. A new hardware transactional memory system called DTM is proposed. DTM performs transaction conflict detection through a separate protocol,which works in a similar way as the traditional directory based cache coherence protocol,but only operates on the transactional states. Test results show that DTM achieves improvement in d... |
