Wavelength signal demodulating is the key techniques to carry out fiber grating sensing network， based on several existing methods of fiber grating sensor demodulation inadequate， a two-match fiber grating demodulation method was presented. This system is a high-speed， high precision， low-cost demodulation system. And by introducing a two-match grating effectively overcomes the problem of double value while expands the scope of testing. This paper analyzes the principle of fiber Bragg grating temperature and gives the software and hardware design of the program. Considering the system of demodulation accuracy and processing speed of FPGA，this paper gives the curve fitting algorithm based on Lagrange.

The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standards, or from scratch, to support a wide variety of custom protocols.The Wizard produces a wrapper, an example design, and a testbench for rapid integration and verification of the serial interface with your custom function Features• Creates customized HDL wrappers to configureVirtex-5 RocketIO™ GTP transceivers• Users can configure Virtex-5 GTP transceivers toconform to industry standard protocols usingpredefined templates, or tailor the templates forcustom protocols• Included protocol templates provide support for thefollowing specifications: Aurora, CPRI, FibreChannel 1x, Gigabit Ethernet, HD-SDI, OBSAI,OC3, OC12, OC48, PCI Express® (PCIe®), SATA,SATA II, and XAUI• Automatically configures analog settings• Each custom wrapper includes example design, testbench; and both implementation and simulation scripts

The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).

Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded and installed the ADOCE SDK from Microsoft, you are ready to use it in your Windows CE Database applications. The sample that I have provided is a *very* simple one illustrating how to instantiate the proper COM objects, and the basics of how to interface with them (in a very simple example)

Tug of War(A tug of war is to be arranged at the local office picnic. For the tug of war, the picnickers must be divided into two teams. Each person must be on one team or the other the number of people on the two teams must not differ by more than 1 the total weight of the people on each team should be as nearly equal as possible. The first line of input contains n the number of people at the picnic. n lines follow. The first line gives the weight of person 1 the second the weight of person 2 and so on. Each weight is an integer between 1 and 450. There are at most 100 people at the picnic. Your output will be a single line containing 2 numbers: the total weight of the people on one team, and the total weight of the people on the other team. If these numbers differ, give the lesser first. )

WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.

浮點數基本運算 浮點數的基本運算主要有四則運算、符號處理、大小比較，以及浮點數分柝等。 包含頭文件 "fn.hpp" #include "fn.hpp" 浮點數基本運算 浮點數的基本運算中有加、減、乘、除、取負、絕對值、相等比較等。 加減乘除 加、減、乘、除四個運算極為相似，都是需要兩個參數，結果當然也是浮點數了。 例子： // 加 減 乘 除 btil::fn::plus<f1, f2>::value // f1+f2 的結果 btil::fn::minus<f1, f2>::value // f1-f2 的結果 btil::fn::multiplies<f1, f2>::value // f1*f2 的結果 btil::fn::divides<f1, f2>::value // f1/f2 的結果 plus<f1, f2>::value::f_val // f1+f2 的結果的值 struct one { static const double f_val = 1.0 } // 兩個浮點數 struct two { static const double f_val = 2.0 } minus<two, plus<divides<one, two>::value, one>::value >::value::f_val == 0.5 取負 取負運算就是取一個浮點數的負數。
