SD卡视频数据存储系统设计

当前,视频数据如何实现快速存储成为研究热点。针对这个问题,本文提出一个SD卡数据存储解决方案。利用FPGA速度快、存储量大、具有可编程性等特点,首先将接收到的视频数据通过外围AD模块,将PAL格式转换为YCb Cr格式,再通过程序设计将YCb Cr格式转换成RGB格式,最后数据存储到SD卡中。设计中通过SOPC定制一个CPU,来控制SD卡数据的读写,使用FIFO控制器、DMA控制器等IP核,有效提高了SD卡读写速度。实验证明所设计的系统能实现视频数据存储功能,与现有SD卡视频数据存储系统相比,该系统具有存储数据格式可变,存储速度快,硬件可重构等特点。

IC卡技术简介

IC卡,是一种将集成电路固封在塑料薄板中的卡片,其外观可以做得类似于磁卡,只是它以电路芯片做为存储信息的媒介而取代磁卡。图1是其外形。IC卡的作用基本和磁卡存储等其它媒介相同。虽然IC卡在国外的发展仅有十年左右的时间,但是成熟地应用在各个行业则是近几年的事情,特别是在法国,应用最为广泛。IC卡最明显的特征:一是存储容量大(2M位IC已面世)。二是保密性好。其存储内容除发卡单位外,不能更改,同时持卡人可以一次性对发卡单位保密地写入密码。     

基于FPGA + SD3.0协议存储速率优化设计

为解决现有存储方案无法满足在特定功能需求下存储速度与设备体积双重要求的问题,本文设计一种基于现场可编程逻辑门阵列（Field programmable gate array, FPGA）控制的SD3.0版本TF卡控制器,旨在占用最小体积的同时实现更高速的数据存储。通过自行设计的小型数据采集卡,将24 bit位宽的数据经过DDR3、FIFO、RAM、两级缓存最终存入TF卡中。分别从硬件、软件两方面介绍了方案的设计,其中硬件部分主要包括电路工艺、采集卡指标与板级信号完整性验证;软件方面主要包括存储流程、RTL级验证与TF卡测试方案。实验结果表明,本文设计的PCB电路可提供SD3.0协议所需的电压转换和数据存储功能,并且板卡功能稳定,集成度较高,部分TF卡测试的速度超过60 MB/s,长时间测试性能稳定,具有良好的通用性,满足设计要求,为小型化存储实验提供了解决方案。

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008

A human-computer interface for non-computer specialists

The COM teleconferencing system was designed to be easy to use for both beginners and people with much computer experience. A number of design choices in organizing the human-computer interface were considered very carefully. These design problems are not unique for teleconferencing applications, but will appear in many other developments of human-computer interfaces for non-computer specialists. This report discusses naming conventions, menu format, user commands, help facility and the treatment of ‘type ahead’ from the users.
