IEEE 802.11g-2003 IEEE Standard for Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements—Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications—Amendment 4: Further Higher-Speed Physical Layer EXTENSION in the 2.4 GHz Band
Top module name : SHIFTER (File name : SHIFTER.v)
2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT.
3. Output pins: OUT [15:0].
4. Input signals generated from test pattern are latched in one cycle and are
synchronized at clock rising edge.
5. The SHIFT signal describes the shift number. The shift range is 0 to 15.
6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it
shifts input data to left.
7. When the signal SIGN is high, the input data is a signed number and it shifts with
sign EXTENSION. However, the input data is an unsigned number if the signal SIGN
is low.
8. You can only use following gates in Table I and need to include the delay
information (Tplh, Tphl) in your design.

利用java實(shí)現(xiàn)文件的AES加密功能
This Java AES Crypt package contains the Java class es.vocali.util.AESCrypt, which provides file encryption and decryption using aescrypt file format.
Requirements
The Java AES Crypt package only works in Java 6, but can be easily adapted to Java 5 by replacing the call to NetworkInterface.getHardwareAddress() with something else.
In order to use 256 bit AES keys, you must download and install "Java Cryptography EXTENSION (JCE) Unlimited Strength Jurisdiction Policy Files" from http://java.sun.com/javase/downloads/index.jsp
VoyagerGX display driver for Windows CE .NET 5.XX
Silicon Motion, Inc. VoyagerGX Driver is architected from the beginning
to support variety of features and EXTENSION of Windows CE .NET, such as
DirectDraw feature, Dynamic Rotation feature, Multimon feature, SMI Multimon
Emulation feature (using single VoyagerGX chip to drive two independent
displays), WCEfA (Windows CE for Automotive) feature, and more
Behavioral models are used in games and computer graphics for
realistic simulation of massive crowds. In this paper, we present a
GPU based implementation of Reynolds [1987] algorithm for simulating
flocks of birds and propose an EXTENSION to consider environment
self occlusion. We performed several experiments and
the results showed that the proposed approach runs up to three
times faster than the original algorithm when simulating high density
crowds, without compromising significantly the original crowd
behavior.
Mobile and wireless communication systems are a prominent communications
technology of the twenty-first century with profound economic and social impacts
in practically all parts of the world. The current state of wireless communication
systems allows for a much wider scope of applications than what it used to be
originally, that is, to be a mobile EXTENSION of the public switched telephone
network.
Welcome to the world of wireless communications and the logical EXTENSION
to the broadband architectures that are emerging as the future of the
industry. No aspect of communications will be untouched by the wireless
interfaces;no part of our working environment will be left untouched either.
As the world changes and the newer technologies emerge, we can expect to
see more in the line of untethered communications than in the wired inter-
faces.
It all started rather innocuously. I walked into Dr GT Murthy’s office one fine day, andchanged my life. “Doc” was then the General Manager, Central R&D, of a very largeelectrical company headquartered in Bombay. In his new state-of-the-art electronics center,he had hand-picked some of India’s best engineers (over a hundred already) ever assembledunder one roof. Luckily, he too was originally a Physicist, and that certainly helped me gainsome empathy. Nowadays he is in retirement, but I will always remember him as athoroughly fair, honest and facts-oriented person, who led by example. There were severalthings I absorbed from him that are very much part of my basic engineering persona today.You can certainly look upon this book as an EXTENSION of what Doc started many years agoin India … because that’s what it really is! I certainly wouldn’t be here today if I hadn’t metDoc. And in fact, several of the brash, high-flying managers I’ve met in recent years,desperately need some sort of crash course in technology and human values from Doc!
