处理器

In terms of memory hierarchy, we investigated how to improve the cache hit rate and localize data according to the characteristics of cache, master memory, local disk and remote disk in cluster systems. As for communication, features of cluster systems and different cluster internal networks are examined. Two popular parallel programming models - message passing model and share memory model - are analyzed in terms of how do they affect the cluster performance and how can we improve the cluster performance.

在处理器层面，分析了现代处理器中常用的一些技术，包括超线程技术、超长指令技术和NUMA架构等，对不同特点的程序的性能影响和如何充分利用处理器中的一些技术提升性能；在存储层次上，结合机群系统上Cache、主存、本地辅存及网络存储的存储层次的特点，分析了数据局部性、Cache命中率等对性能的影响以及提出如何提高数据局部性；通讯系统层面分析了不同机群通讯系统及不同机群通讯网络的特点；在编程模式方面，分析和比较了目前最常用两种并行编程模式--消息传递编程模式和共享存储编程模式，在机群系统上对性能的影响因子以及提出如何提高性能的方法。

This is not the first case of radical chngein plans with respect to the release of processors with the architecture core - for a while back intel forewent the release of single core processors pentium e1xxx, after giving preference to close ones in the characteristics by dual core to the processors pentium e2xxx.

这并非首例，在激进细胞学图就释放处理器的架构芯为前阵子forewent释放单核心英特尔奔腾处理器e1xxx，接近鸡舍后，优先采用双核心的特点e2xxx奔腾处理器。

The development direction changed direction according to the four-wheeler, the domestic and international company changes direction organization to control to the four-wheeler currently main adoption of is a numeral control, this is owing to a lot of advantages of numerical control:the procedure turn a control, the controller carries on the processing of operation and numerical information according to the control regulation designed, mainly passing procedure to carry out, if change control regulation need to change software, but need not change the hardware structure of system: control the accuracy is high, in the emulation the control the system, the accuracy of the controller from the accuracy of the component but settle, numerical controller accuracy from word long decision;Stability good;The software replies to use, needing a hardware environment of using the homology realization in the emulation the system, the numerical controller is a procedure control, the sub- procedure mold piece which need to be designed and write to carry out its model, can immediately carry out several links of functions expediently.

目前各个厂家大多采用的是PLC、单片机应用于四轮转向控制器中，功能基本能够实现，相比较之下，信号处理能力较强的数字信号处理器各方面均性能优于以上三种处理器。DSP是新世纪数字化革命的核心。它是一种独特的微处理器，具有可编程性，且实时运行速度远远超过通用微处理器。强大的数据处理能力和高速的运行速度，是DSP最值得称道的两大特色。DSP芯片是一种特别适合进行数字信号处理的微处理器。它强调运算处理的实时性，因此除了具备普通微处理器所强调的高速运算和控制功能外，主要针对实时数字信号处理，在处理器结构、指令系统和数据流程上做了很大的改动。它具有灵活、精确、可靠性好、体积小、功耗低和易于大规模集成等优点。

Each Xbox game is written with specific Xbox hardware in mind, and the 360's move to PowerPCs and ATI graphics doesn't jibe with the Xbox's Intel chips and Nvidia graphics processors.

每一个XBOX游戏是用XBOX的硬件来编写的，而使用POWERPC和ATI图形处理器则与XBOX的INTEL处理器和NVIDIA图形处理器有很大的不同。

This dissertation introduces the developmental status of the LLL processing technology research and the history of the development of DSP.

论文介绍了微光图像处理技术的发展状况，结合高速数字信号处理器的发展历史，在对基于高速数字信号处理器的微光视频图像处理器的硬件实现方案研究的基础上，重点进行了系统软件的研究与设计。

Each processor is assigned a specific task; master processor schedules and allocated work to slave processors.

每个处理器赋予一个特定任务；主处理器为从处理器调度和分配作业

Each processor is assigned a specific task; master processor schedules and allocates work to slave processors.

每个处理器赋予一个特定任务；主处理器为从处理器调度和分配作业

Utilization of the slave processor might be poor if the master processor does not service slave processor requests efficiently.

如果主处理器未能有效地满足从处理器的请求，那么从处理器的利用率就会很低。
