查询词典 cache

According to one embodiment, a method of coherency management in a data processing system includes holding a cache line in an upper level cache memory in an exclusive ownership coherency state and thereafter removing the cache line from the upper level cache memory and transmitting a castout request for the cache line from the upper level cache memory to a lower level cache memory.

根据一个实施例，数据处理系统中一致性管理的方法包括：在处于独占所有权一致性状态的较高级别高速缓存存储器中保存高速缓存线，以及其后从较高级别高速缓存存储器移除高速缓存线，并且从较高级别高速缓存存储器发送对高速缓存线的掷出请求到较低级别高速缓存存储器。

NRS4000是一个32位的嵌入式RISC产品，时钟频率为20MHz，采用5级流水技术，实现了面向寄存器的指令集（共128条指令），支持了寄存器窗口切换和基于优先级的中断、故障、跟踪、通信等功能，是一个完整的微处理器系统。

The failure rate; that failure rate monitor is unit trends monitoring to apply below distinct Cache size with the process and the Cache that increase advantageous position differentiates algorithm expanded the Cache with conventional optimum failure rate differentiates algorithmic, numerary of Cheng of basis application line differs to give application to gift when undertaking Cache differentiates different power worth, the application that has more line Cheng in order to make obtains more sharing Cache, improve integral performance of the system thereby.

失效率监控器以进程为单位动态监控在不同的Cache容量下应用的失效率；而加权Cache划分算法扩展了传统的失效率最优的Cache划分算法，根据应用线程数目的不同在进行Cache划分时给应用赋予不同的权值，以使具有更多线程的应用获得更多的共享Cache，从而提高系统的整体性能。

There used to be two primary methods to optimize program data locality: the first is to analyze cache behavior of program data, then basing on cache behavior model, build a program analysis tool which shows the bottlenecks of data cache performance and hence directs programmer to tune performance of data cache; the second is program transformation by an optimizing compiler or an optimizing tool, and data cache performance is optimized in the transformation.

过去在这方面的工作有两个重要的思路：一是针对程序运行时的访问数据，利用相关的Cache行为模型，建立一些程序分析工具，从源代码级给出程序Cache性能的瓶颈，指导程序员通过程序变换来优化程序的局部性，从而提高Cache性能；二是在编译器上开发编译优化过程，或者开发专门的程序优化工具，通过对程序进行分析，在此基础上自动进行程序变换，包括代码变换和数据变换两种，优化程序的局部性，从而提高 Cache性能。

The characteristics of FIFO, double-port RAM and ping-pang cache structure were compared. The principle and features of ping-pang cache structure were discussed, and a real ping-pang cache structure was also given which consisted of high-speed, large capacity SRAM and FPGA. For a video processing system, this ping-pang cache structure is easy to interface with AD, DA and DSP.

文中比较了FIFO、双口RAM、乒乓缓存结构三种数据缓存电路的优缺点，讨论了乒乓缓冲控制器的结构和原理，并以高速、大容量的SRAM 以及FPGA器件为基础，设计了一种适应于高速DSP图像处理系统的乒乓缓存结构，其特点是速度快、所需器件少，易于与DSP器件接口。

网通分别放一个缓存服务器，用户实际访问缓存服务器，缓存服务器再原网站服务器读取内容，并将已经读取的内容缓存到本地。

This defines the path to cache directory, cache directory name, type and size of the cache area.

定义了到缓存目录的路径、缓存名称、类型以及缓存区域的大小。

Large-capacity hard disk cache can read and write in the work of state, so that more data is stored in the cache to improve disk access speed, but does not mean that the bigger the cache the more outstanding.

大容量的缓存虽然可以在硬盘进行读写工作状态下，让更多的数据存储在缓存中，以提高硬盘的访问速度，但并不意味着缓存越大就越出众。
