摘　　要：为了研究多核处理器系统上的并行编程问题,开展了对事务存储模型的研究。阐述了事务存储,介绍了事务存储系统的实现方法,利用4种事务存储系统详细阐述了事务存储的实现;重点讨论了6种影响事务存储发展的关键技术,即实现方式、数据结构组织、并发控制、冲突检测、争用管理等;提出了事务存储将向着软硬件结合、提升性能、提高正确性和满足多核应用需求的方向发展。To invertigate a problem on parallel programming in multi-core processor system, transactional memory is researched. Firstly, tranctional memory and its implementation way are introduced. Then, the implementation of transactional memory is clarified by introducing different transactional memory systems. Six key technologies are discussed, such as implementation way, data structure organization, concurrent control, nonblocking synchronization, conflict detection, contention management. Finally, the development trends of transactional memory is presented including software-hardware combination, increasing performance and correctness, and adapting the multicore application.
