Processor Speculative & pipeline

1. 使用DS-5 Streamline定位瓶颈 DS-5 Streamline要求GPU驱动启用性能测试,在Mali GPU驱动中激活性能测试对性能影响微不足道. 1.1 DS-5 Streamline简介 可使用DS-5 Streamline从CPU和Mali GPU中实时收集性能计数器,然后以图形方式显示这些计数器,其主要功能如下:     ? 收集计数器--从CPU和Mali GPU中     ? 保存收集到的计数器数据以供回放     ? 查看显示GPU活动.GPU活动和Framebu

路由启动由CamelContext的start()方法开始,在该方法中调用了super.start(),即调用父类ServiceSupport的start()方法,ServiceSupport的start()方法中调用了doStart()方法又回到CamelContext的doStart()方法,该方法中调用了doStartCamel()方法,在doStartCamel()方法中有两个最重要的方法:startRouteDefinitions()与doStartOrResumeRoutes()方法

An apparatus and method is described herein for providing robust speculative code section abort control mechanisms. Hardware is able to track speculative code region abort events, conditions, and/or scenarios, such as an explicit abort instruction, a

A?system?management?mode?(SMM) of operating a processor includes only a basic set of hardwired hooks or mechanisms in the processor for supporting SMM. Most of SMM functionality, such as the processing actions performed when entering and exiting SMM,

A method and apparatus for executing lock instructions speculatively in an out-of-order processor are disclosed. In one embodiment, a prediction is made whether a given lock instruction will actually be contended. If not, then the lock instruction ma

A speculative?store?buffer is speculatively updated in response to speculative store?memory operations buffered by a?load/store?unit in a microprocessor. Instead of performing dependency checking for?load?memory operations among the?store?memory oper

In one embodiment of the present invention, a method includes switching between a first address space and a second address space, determining if the second address space exists in a list of address spaces; and maintaining entries of the first address

BACKGROUND Many modern operating systems (OS's) use the Advanced Configuration and Power Interface (ACPI) standard, e.g., Rev. 3.0b, published Oct. 10, 2006, for optimizing system power. An ACPI implementation allows a processor core to be in differe

It’s been awhile since I posted something here, and I figured I might use this spot to explain some general points about graphics hardware and software as of 2011; you can find functional descriptions of what the graphics stack in your PC does, but u
