视频存储器

In this paper, an address mapping method for multi-standard video is presented, which maps video picture into the memory space of DDR SDRAM with a simple formula.

提出了一种支持多标准视频的存储器地址映射方法，用一个简洁的公式把视频图像映射到DDRSDRAM的存储空间。

Video Dynamic Random Access Memory?

视频动态随机存取存储器？

In information processing, especially realtime video image processing usually have to deal with video images, which must first be designed largecapacity memory, synchronous dynamic random access memory SDRAM Although there are low cost, large capacity, etc., but SDRAM control structure of the complex, commonly used method is to design generic SDRAM controller, which makes a lot of people had to abandon the use of SDRAM and the use of expensive SRAM.

在信息处理中，特别是实时视频图像处理中，通常都要对实现视频图像进行处理，而这首先必须设计大容量的存储器，同步动态随机存储器SDRAM虽然有价格低廉、容量大等优点，但因SDRAM的控制结构复杂，常用的方法是设计SDRAM通用控制器，这使得很多人不得不放弃使用SDRAM而使用价格昂贵的SRAM。

There is no definition of the electronic evidence provided by laws, and the electronic evidence discussing here is computer evidence, which is generated in the operating process of computer or network system, stored as digital format in the computer memory or external storage medium, and testifying the facts by its digital data or information. It is manifested as E-mail, electronic bulletin board, electronic document, electronic signature, electronic chatting record, web-page, web-video, database, etc.

我国法律法规对电子证据并无定义，本文探讨的电子证据是指计算机证据，即在计算机系统或者网络系统运行过程中产生的、以数字形式保存在计算机存储器或外部存储介质中、能够证明案件真实情况的电子数据或信息，其表现为电子邮件、电子公告板、电子文档、电子签名、电子聊天记录、网页、网络视频、数据库等多种形式。

A system for playing the digital video frequency with a changable playing back speed comprises: an acquiring module for acquiring the coded picture from the data memorizer; and a distributor module for selectively deleting the coded picture from the input high-speed buffer.

一种以变化的回放速度播放数字视频的系统可以包括：获取器模块，配置用于从数据存储器中获取编码后的画面；以及分配器模块，配置用于从输入高速缓冲器中选择性地删除编码后的画面。

To perform an NR processing and an enlarging/reducing processing of a video signal, an NR buffer (104) is composed of, e.g., five line memories.

在进行视频信号的NR处理和放大缩小处理的情况下，NR缓冲器(104)由例如5个行存储器构成。

I found the VRAM and was able to write a small task that monitors the audio levels at 30 Hz and draws a very simple level meter on the top of the screen.

我发现视频存储器，并能够写一个小的任务，各级监察音频为30赫兹，并提请一个非常简单的一级米的画面上方的。

While some use dynamic RAM , higher-quality video cards use video RAM or VRAM to improve the quality of graphics .

有些视频卡使用动态随机存储器，而一些高质量的视频卡使用视频RAM即VRAM以改善图形质量。

Firstly it introduces relevant technical developments and trends, the task background and significance of the study, then analyzes hardware circuit of using image sensor as images collected, and utilizes the SAA7113 chip to deal with video image beforehand, SAA7113 lets the output of standard digital video signals to storage in FIFO memory, and decodes clock signals, Highlighted microprocessor control external circuit design of false coin and counting, and DSP control external circuit design, such as memory expand ect;Finally analyses CPLD as logic controller to control the logic and scheduling of some part ,and gives the undee emluator of some logic circuit.

文章首先阐述人民币智能分捡器相关技术的发展状况、发展趋势以及课题背景与研究意义；然后设计了利用图像传感器采集人民币图像输出模拟视频信号的硬件电路，以及利用视频解码芯片(SAA7113)对模拟视频图像进行预处理，SAA7113输出的标准数字视频信号存入FIFO存储器，同时还解码输出场、行同步信号、像素时钟信号送入CPLD等部分电路；重点设计了单片机控制验钞、点钞等外围电路，以及DSP控制的外围电路，如存储器的扩展等部分；最后完成CPLD对部分器件的逻辑和时序控制设计，并对逻辑电路的功能进行仿真，仿真结果令人满意。

The main difference in this configuration is that the video digitization is being performed at the camera level, and the computer network is being used to transfer the picture back to the pc-based server for storage.

主要不同在于在这样的配置中，视频采集的数字化在前端摄像机实现。计算机网络被用于传输图像，传到基于pc的存储器中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
