Into memory,Direct memory access,DMA,is a method used to

直接存储器访问就是在数据传输中绕过 CPU

This feature is for the hard disk and CD-ROM drive Direct Memory Access (DMA, Direct Memory Access acronym) to maximize system performance upgrade, because personal computers are now the biggest bottleneck is the disk input and output.

这个特性是针对硬盘以及光盘驱动器的直接存储器访问(DMA，Direct Memory Access的缩写)来最大限度提升系统性能，因为现在个人计算机的最大瓶颈就是在磁盘的输入输出上。

Memory access speed is much higher than the disk, if the memory read and write as a disk cache can effectively improve the efficiency of system operation.

内存的读写速度比磁盘高得多，如果将内存作为磁盘读写的高速缓存可以有效提高系统运行效率。

In this system, we introduces cluster architecture to provide global and scalable streaming caching proxy service mechanism; We implement streaming media transfer protocol on caching proxy end; We implement layered caching mechanism (global disk caching and memory caching) using dynamic sharing running memory buffer algorithm to support more stable and real-time parallel streams; We implement client request aggregation by means of streaming session sharing to reduce disk I/O and serve more user; We propose single streaming image to support the unify of pre-fetching streaming and caching streaming, which guarantees the proxy streaming of transparency for client; We design and implement streaming pre-fetching mechanism based on packet feedback information to reduce the number of "rebuffering" on client end; We bring forward streaming caching admission control policy fit for streaming caching proxy server to guarantee the QoS of streaming service.

该系统引入集群架构以提供全局的、可扩展的缓存代理服务机制；实现了缓存代理端的流媒体传输协议；采用动态共享运行缓冲区算法实现了分层缓存机制(全局磁盘缓存和内存缓存)以支持更多稳定、实时的并发流；利用流会话共享机制实现了客户请求聚集，从而减少磁盘I/O同时能服务更多的客户；提出了单一流映像，以支持预取流和缓存流的统一，从而保证代理端服务流对客户的完全透明；设计并实现了基于包反馈信息的流数据预取机制，从而减少了客户端的"rebuffering"次数；提出了适合于缓存代理服务器的流缓存准入控制策略，保证了流服务的QoS。

Embedded systems are usually diskless systems. In order to keep permanent data in the systems, it is a widely adapted strategy to use flash memory disk as its disk system, therefore how to build a flash memory file system is the focus of this thesis in a reasonable embedded system.

嵌入式系统通常是无磁盘系统，为了让嵌入式系统能够永久性保存资料，使用Flash 存储器是一种普遍的策略，那么如何在嵌入式系统环境中建立Flash 存储器文件系统就成为了本文研究和解决的重要问题。

YAMD is one very effective memory debugging tools can be used under Linux Debugging Memory divulged.

YAMD 是一款很有效的内存调试工具，能够用于linux下内存泄露的调试。

①By comparing 3 memory systems on how long does the information support, it is proved that yellow Dolor integration of red and green produces in the sensory memory.

①颜色通过对照大脑三个记忆系统对信息的维持时间，确定红绿颜色融合成黄色是在感觉记忆中实现的。

A new and efficient learning algorithm of asociative memory neural network is proposed, with the following characteristics:(1)it can store any given training pattern set no matter how much and what correlation among them may be;(2)the smallest domain of attraction of training patterns is maximized;(3)each domain of attraction of training patterns is guaranteed to be as large as possible;(4)the designed associative memory network is globally stable.

摘要提出一种新的联想记忆网络模型的有效学习算法，它具有下述特点：(1)可以全部存储任意给定的训练模式集，即对于训练模式的数目和它们之间相关性的强弱没有限制；(2)最小的训练模型吸引域达到最大；(3)在(2)的基础上，每个训练模式具有尽可能大的吸引域；(4)联想记忆神经网络是全局稳定的。

So, the memory effects of the nonvolatile memory device can be improved by using the double layer nanocrystals.

所以，藉由双层的奈米点可以有效增进奈米点记忆体的记忆效应。

The downsize to SuperFetch is that it takes memory, in fact, it uses lots of memory resource.

的缩小，以SuperFetch是，它需要记忆，事实上，它使用大量的记忆体资源。

"The operators will suffer a temporary decrease in the number of consumers and short message services as people may not like having to provide their ID cards for a phone number," Xu Junqi, vice-dean with the Policy-Making Institute of the Telecommunications Research Centre under MII, said yesterday.

信息产业部下属的通信决策研究院副主任徐俊其昨天说：&实行手机实名制后，人们可能不太情愿用身份证注册手机号，所以通信运营商会暂时面临用户减少和短信用户减少的问题。&
