In a simultaneous multithreaded processor, improving the throughput of the instruction fetch unit usually means that there is more drastic cache competition between threads, but this competition limits the throughput reversely.

在同时多线程处理器中,提高取指单元的吞吐率意味着各线程之间的Cache竞争更加激烈,而这种竞争又制约着取指单元吞吐率的提高。

In Simultaneous Multithreading(SMT)processors,the instruction fetch policy determines the way of allocating shared resources among co-scheduled threads implicitly,and affects throughput and fairness consequently.

同时多线程(SMT,Simultaneous Multithreading)处理器中,取指策略隐式的决定了共享资源在线程之间的分配,进而决定了吞吐量和公平性。

Next,an ideal fetch model of instruction fetch policy is given,and a realistic policy named IPCBFP,based on the ideal model,is proposed and analyzed.

文中简单介绍了SMT技术,讨论了常用的取指策略,比较了各策略在提高性能方面的优劣。

In this paper,a QoS capable fetch policy for SMT processors is proposed and the related issues about QoS management are discussed.

建议了一种具有QoS特性的同时多线程处理器取指策略,并讨论了其在QoS管理方面的问题。

In this paper,we propose a novel fetch policy called MFP(Multiple Fetch Priorities) to prevent the negative effects caused by L2 cac.

本文提出了一种基于多个取指优先级的同时多线程取指策略MFP(Multiple Fetch Priorities),用于减少L2 cache失效给处理器性能带来的负面影响。
