| 摘 要： | 现代多核处理器结构的设计使得集成在同一块芯片上的多个执行核共享各种硬件资源,如片上最后一级Cache、内存控制器、前端总线以及硬件预取单元等,而多线程的并行执行导致核与核之间其享资源的争用,造成系统整体性能的下降,如何有效地解决多核共享资源冲突来提升系统的整体性能以及应用程序的服务质量成为当今研究的热点.文章首先概要介...

| Abstract: | Modern multi-core processors are designed with multiple cores integrated on a chip,one common feature of these multi-core chips is resources sharing among sibling cores that sit on the same chip,such as the last level Cache,memory controller,front-side bus and prefetching hardware.The parallel execution of multiple threads leading to the contention of shared resources,causing a degradation of the system performance.Therefore,How to solve the contention for shared resources effectively and improve overall sy... |
