C syntax simplifies many of the complexities of c while providing powerful features such as nullable value types , enumerations , delegates , anonymous methods and direct memory access , which are not found in java C #语法简化了c + +的诸多复杂性，同时提供了很多强大的功能，例如可为空的值类型、枚举、委托、匿名方法和直接内存访问，这些都是java所不具备的。
Msil includes instructions for loading , storing , initializing , and calling methods on objects , as well as instructions for arithmetic and logical operations , control flow , direct memory access , exception handling , and other operations Msil包括用于加载、存储和初始化对象以及对对象调用方法的指令，还包括用于算术和逻辑运算、控制流、直接内存访问、异常处理和其他操作的指令。
A common data acquisition card can be used on laboratory virtual instrument engineering workbench through designing the external interface between labview and common date acquisition card on the software design ; used the idea of the double buffer and direct memory access , a real time data acquisition and logging about the succession , big capacitance leakage current is realized ; a digital filter is designed to filter high frequency signals 在软件设计上，设计了与普通数据采集卡的接口，实现了在labview环境中应用普通数据采集卡的功能；运用双缓冲和内存直接映射的设计方法实现对连续、大容量泄漏电流信号的实时采集和存储；设计了数字滤波器对采集后的原始数据滤去高频干扰。
In this system , it is master - slave structure between pc and dsp . dsp transfers data to pc by adopting the dmac ( direct memory access controller ) in pc . the thesis dwells on every part of hardware circuit and main technology such as dsp , the transferring mode of dma ( direct memory access ) , etc subsequently , it introduces the software design of the sampling system and user interface 该最小系统制作成高速数据采集卡，插入pc机的isa总线插槽中， pc机与dsp构成主从结构，系统中tms320f240dsp作为pc机的下位机，采用pc机内的dmac ( dma控制器)通过dma (直接存储器存取)方式把采集的数据传送到pc机进行处理。
It has been developing quietly ever since the men of principle began to fear that their revolution would not survive the encroachment of western ideas , consumer habits , satellite television and the rise of a generation that had no direct memory of either revolution or war 随着伊朗到处都充塞着西方思想、消费者习惯与卫星电视，并且还迎来了新一代伊朗人的崛起，一代对革命或战争没有切身记忆的人，那些原则性强的人便开始担心他们的革命并不能成功，而到目前为止，革命只是一直在悄无声息地进行着。
In order to deal with those problems above , a video surveillance scheme based on dsps was presented , which used high performance dsps to replace pc as central control unit . not only did we realize the hardware circuits of the system , but also we developed it ' s software . furthermore , three essential methods , for instance the data transfer method by extend direct memory access ( edma ) , buffer management method by three buffer strategy and optimized data acquire method had been discussed 为了弥补这些不足，论文采用高性能的dsps取代传统的pc作为核心处理器，设计了一种基于dsps的交通视频监控系统的图像处理平台，详细的对其硬件实现和软件调试进行了论述；在这个基础上分析了视频图像采集和处理的流程，讨论了一种利用edma的实时后台传输数字视频方法和三帧缓冲的存储器管理方法，为系统的实时性提供了保障。
