Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is done using a tree of carry save adders to ensure the high speed processing required for many applications. The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis reveals that the proposed architecture, implemented using current VLSI technologies, can process a video stream in real time.

JavaTV Program source code Need to play Windows Media files and streams, mpeg4 video or DVDs in java? Access WDM capture devices? Control a firewire DVCam? Then maybe this can help you. dsj is an ongoing project to provide a java wrapper around Microsoft s DirectShow API. It offers a set of high level classes that give java easy access to functionality widely missed by java programmers and also lets you dive deeper into the interiors of Windows core api for 2D media. On the java side dsj tries to keep things open as possible - you may use it standalone or let it feed data into JMF or other APIs.

Design Specification Introduction Goals and Objectives GameForge is a graphical tool used to aid in the design and creation of video games. It attempts to bring game development down to a level that any computer savvy user can understand, without requiring masterful programming ability. A user with limited Microsoft DirectX and/or Visual C++ programming knowledge will be able to construct a basic, 2-D arcade game. GameForge limits the amount of actual code written by the user, if not eliminating it completely. It will also assist experienced programmers in generating the Microsoft DirectX and Microsoft Windows9x overhead necessary for basic game construction, allowing them to concentrate on more detailed game design issues and implementation.

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)

用汇编语言做的一个打字游戏。运行环境是MASN5.0。 1,用户打开软件时先出现欢迎界面,当用户输入字符’1’时,再进入打字界面 当用户按的是”ESC”键时,退出打字游戏 当用户输入不是数字”1”或者不是按的”ESC”键时,屏幕不动作,直到用户输入数字”1”或者按的”ESC”键时 2,打字字符从第二行开始显示(双数行为显示打字内容,单数行由用户输入) 打字内容:1), We will see his boat and then.We ll say goodbye to him. 2), He ll be away for two months.We are very proud of him. 3,用户输入的和上一行相对应相等时,表示输入正确,否则输入错误,则显示’#’ 当用户按下”ESC”键,退出打字程序 4,显示用户打字的正确性,假如错误数小于10字符,显示” Very Good!” 否则显示” Very Bad!” 5,当用户输入一次时,假如用户还想重新打字游戏,请按数字键”3”,否则按”ESC”键退出打字程序
