COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION Hardware-based solutions are generally referred to as cache coherence protocols. These solutions provide dynamic recognition at run time of potential inconsistency conditi…

COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION In contemporary multiprocessor systems, it is customary to have one or two levels of cache associated with each processor. This organization is essential to achieve reason…

COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION Software cache coherence schemes attempt to avoid the need for additional hard-ware circuitry and logic by relying on the compiler and operating system to deal with the pr…

A cache coherence protocol facilitates a distributed cache coherency conflict resolution in a multi-node system to resolve conflicts at a home node. FIELD The invention relates to high-speed point-to-point link networks. More particularly, the invent…

COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION To provide cache consistency on an SMP, the data cache often supports a protocol known as MESI. For MESI, the data cache includes two status bits per tag, so that each lin…

Textbook:<计算机组成与设计——硬件/软件接口>  HI<计算机体系结构——量化研究方法>          QR 最后一节来看看如何实现parallelism 在多处理器系统中,每个处理器(core)可能有自己专属的cache,然后多处理器共享memory.在这种情况下,当多个线程(核心)对同一个变量进行读写时,就会出现不同cache中该变量的值不一样的情况(取决于cache是write back还是write through,以及相关cacheline被evict的时间…

A pending tag system and method to maintain data coherence in a processing node during pending transactions in a transaction pipeline. A pending tag storage unit may be coupled to a cache controller and configured to store pending tags each indicativ…
