数控分频器设计:对于一个加法计数器，装载不同的计数初始值时，会有不同频率的溢出输出信号。计数器溢出时，输出‘1’电平，同时溢出时的‘1’电平反馈给计数器的输入端...

用ALTERA的FPGA实现UDP通信源代码(FPGA UDP)

该源码为VHDL语言编写的分频器，在W-4b教学平台上通过验证-The VHDL source for the prescaler languages, W-4b in the teaching platform validated

说明：  Objects forming possible solution within original problem context are called phenotypes, their encoding, the individuals within the GA, are called genotypes. The representation step specifies the mapping the phenotypes onto a set of genotypes. Candidate solution, phenotype and individual are used to denotes points of the space of possible solutions. This space is called phenotype space. Chromosome, and individual can be used for points in the genotye space. Elements of a chromosome are called genes. A value of a gene is called an allele. Variation Operators The role of variation operators is to create new individuals old ones. Variation operators form the implementation of the elementary steps with the search space.

说明：  matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

利用fpga实现gmsk的调制并仿真，全部代码(Fpga implements gmsk)

This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file. Compression ratio is fixed for IMA-ADPCM, being 4:1.
