To increase simulation speed, ModelSim® can apply a variety of optimizations...

The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.

在QuartusII下进行编译和仿真的时候,会出现一堆warning,有的可以忽略,有的却需要注意-QuartusII warning solving

基于FPGA的图像压缩算法程序，自己写的，可以参考一下(FPGA-based image compression algorithm, write your own, you can refer to)

说明：  等精度测频法，有需要的可以下载看看哟，word中包含的代码(Equal Precision Frequency Measurement Method)

说明：  SimpleVOut (SVO) is a simple set of FPGA cores for creating video signals in various formats. The cores connect using AXI-streams. Most configurations (resolution, framerate, colordepth, etc.) are set at compile-time using Verilog parameters. See svo_defines.vh for details on those parameters.

说明：  基于FPGA，用verilog hdl语言实现串口收发实验(Based on FPGA, using Verilog HDL language to achieve serial port transceiver experiment)

说明：  潘松那本书上用vhdl语言描述的16位并入并处加法器(Pan book vhdl language used to describe the 16-bit adder into his)

用VHDL语言写的代码 包括全局的输入时钟缓冲器来去抖动，块RAM模块65536*10，读数据，写数据，空标志信号的产生，满标志信号的产生，读写使能信号的产生七个模块！对各位有帮助噢！

资源描述该程序可以读写FAT32文件系统的SD卡。SD卡的接口现在采用IO模拟接口方式。在板子SD卡座上插上FAT32格式的SD卡，请连接下载线的JTAG接口到板子，下载fpga的SOF文件，再下载NIOSII IDE中的文件。
