| 摘 要： | 作为计算机体系结构核心问题之一的存储一致性研究主要是围绕CPU访存一致性问题展开的,I/O设备DMA操作引发的存储一致性问题则一直处于研究的边缘。从I/O与存储体系结构一体化设计理念出发,针对支持全局DMA访问的分布共享存储(DSM)系统存储一致性问题,研究广义存储一致性,定义了涵盖I/O的广义程序概念,建立了广义域存储一致性模型,研究了基于广义域存储一致性模型的Cache-Memory-I/O一致性协议实现技术,对于DSM系统实现全局共享I/O具有指导意义和参考价值。

| Abstract: | Memory consistency research,as one of the core issues of computer architecture,mainly focused on the CPU access memory,while the consistency issues of DMA operations is seldom studied.According to the idea of integrating the architecture design of I/O and memory,the paper defines the concept of general program included I/O operations,aimed at the consistency issues of DSM(distributed shared memory) systems with global DMA operations.The paper studies the general memory consistency model,and builds the gener... |
