说明：  随着人们对光谱测量仪器灵活性、 微型化的要求 ,便携式光纤光谱仪在实际生产测量中的需求也越来越大 ,对其测量性能的要求也越来越高。根据光纤光谱仪的测量原理 ,利用波长与CCD探测器单元格一一对应的关系 ,提出了一种波长校正的方案 ,波长校准精度可以达到0.5nm ,重复性达0.1nm。(Wit h people′ s requirement for spect rometer are agility and micromation , portable fiber spect rometer is needed more and more widely in practical measurement , and t he requirement for it s measurement capability get s more and more higher . According to t he measurement principle of t he fiber optic spect rometer and the cor responding relationship between t he wavelengt h and the CCD detector′ s cell , a wavelengt h correction met hod is p ut forward in t his paper , t he wavelengt h p recision can reach 0. 5nm and t he repeatability can reach 0. 1 nm.)

Ultimate CRC is a CRC generator/checker. Using generics the core can be fully customized. It creates a function of the data input and the CRC register using XOR-logic. Although the levels of logic gets very high for wide data inputs, the throughput still benefits from this architecture, as can be seen from the synthesis page.

一个以太网帧解析程序，实现以下功能：解析已封装好的Ethernet V2.0帧封装文件（见附件），判断有多少个帧，每个帧的所有字段内容，检测CRC校验是否正确(An Ethernet frame analysis program, the following functions: parsing the encapsulated Ethernet V2.0 frame encapsulation (see annex), to determine the number of frames, each frame contents all fields to detect CRC checksum is correct)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
