ADM6993F/FXFiber to Fast Ethernet Converter (TS1000 CPE Complied) The ADM6993F/FX is a single chip integrating two 10/100 Mbps MDIX TX/FX transceivers, a three-port 10/100M Ethernet L2 switch controller, and one OAM engine to meet demanding applications, including Fiber-to-Ethernet media converters, especially the fiber to the home (FTTH) media converters. The ADM6993F/FX feature Set includes link pass through (LPT), TS1000 OAM frame receiving/processing/transmitting, programmable link status LED display, various loop-back modes, and one configurable MII ports for snooping/inserting OAM frame from/to 100Fx. The ADM6993FX is the environmentally friendly “green” package version.

this directory contains the following: * The acdc algorithm for finding the approximate general (non-orthogonal) joint diagonalizer (in the direct Least Squares sense) of a Set of Hermitian matrices. [acdc.m] * The acdc algorithm for finding the same for a Set of Symmetric matrices. [acdc_sym.m](note that for real-valued matrices the Hermitian and Symmetric cases are similar however, in such cases the Hermitian version [acdc.m], rather than the Symmetric version[acdc_sym] is preferable. * A function that finds an initial guess for acdc by applying hard-whitening followed by Cardoso s orthogonal joint diagonalizer. Note that acdc may also be called without an initial guess, in which case the initial guess is Set by default to the identity matrix. The m-file includes the joint_diag function (by Cardoso) for performing the orthogonal part. [init4acdc.m]

RSA算法是第一個能同時用于加密和數字簽名的算法，也易于理解和操作。RSA是被研究得最廣泛的公鑰算法，從提出到現在已近二十年，經歷了各種攻擊的考驗，逐漸為人們接受，普遍認為是目前最優秀的公鑰方案之一。RSA的安全性依賴于大數的因子分解，但并沒有從理論上證明破譯RSA的難度與大數分解難度等價。即RSA的重大缺陷是無法從理論上把握它的保密性能如何，而且密碼學界多數人士傾向于因子分解不是NPC問題。 RSA的缺點主要有：A)產生密鑰很麻煩，受到素數產生技術的限制，因而難以做到一次一密。B)分組長度太大，為保證安全性，n 至少也要 600 bits 以上，使運算代價很高，尤其是速度較慢，較對稱密碼算法慢幾個數量級；且隨著大數分解技術的發展，這個長度還在增加，不利于數據格式的標準化。目前，Set( Secure Electronic Transaction )協議中要求CA采用比特長的密鑰，其他實體使用比特的密鑰

Atheros Communications AR6001 WLAN Driver for SDIO installation Read Me March 26,2007 (based on k14 fw1.1) Windows CE Embedded CE 6.0 driver installation. 1. Unzip the installation file onto your system (called installation directory below) 2. Create an OS design or open an existing OS design in Platform Builder 6.0. a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items). b. Run image size should be Set to allow greater than 32MB. 3. a. From the Project menu select Add Existing Subproject... b. select AR6K_DRV.pbxml c. select open This should create a subproject within your OS Design project for the AR6K_DRV driver. 4. Build the solution.

The code on this diskette has been organized by chapter. Each subdirectory containing listing has a readme.txt describing program usage and any relevent file formats. The readme will also describe how to compile the target programs under IBM OS/2 (TM) using the using C Set++ compiler (TM). All programs on this diskette have been compiled and tested in this environment. The majority of programs on this diskette should port to other environments with only minor adjustments. The exception to this are those programs which utilize presentation manager for graphical display of program data. In particular, the grid1 programs in \chapt4\backprop\ and \chapt3\ fall into this latter category.

A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, Set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.
