很不容易找到的资料，基于VHDL的频率计设计 希望有用

vhdl code for cyclic cfft control

this is bpsk code in matlab

verilog coding for butterworth filter with cut off frequency with 500hz

用verilog编写的lms算法。可实现自适应滤波功能(Lms algorithm written in verilog. Adaptive filtering can be achieved)

多进制数字频率调制(MFSK)系统VHDL程序-Multi-band digital frequency modulation (MFSK) system VHDL procedures

扰码器的verilog实现,参考802.11a相关标准-Scrambler in verilog implementation

实施软件定义无线电的关键第一步是向与数字到模拟控制器接口。好花费的时间是在这工作，因为驾驶 DAC 的信号的时间必须是正确的设备才能正常工作。Spartan3e 培训师局是有 LTC2624 DAC 连接到通过 SPI 总线 FPGA。用于进行通信的 DAC 的信号是 SPI_MOSI、 DAC_CS、 SPI_SCK、 DAC_CLR。下表中描述的接口信号。

QuartusII简介手册+中文版 本手册针对的读者是 Quartus II 软件的初学者，它概述了可编程逻辑设计中 Quartus II 软件的功能。 不过，本手册并不是 Quartus II 软件的详尽参考手 册。 相反，本手册只是一本指导书，它解释软件的功能以及显示这些功能如 何帮助您进行 FPGA 和 CPLD 设计。-QuartusII brochure+ Chinese version of the manual is aimed at readers of Quartus II software for beginners, it provides an overview of programmable logic design in Quartus II software. However, this manual is not the Quartus II software, a detailed reference manual. Instead, this manual is a guide book, which explained the functions of the software and show how these features help you to FPGA and CPLD design.

一个计算机原理课程设计的作业，5级流水线CPU，指令集到代码均为自己设计，有最终报告文档，组建说明，并行除法，16位字长，定长指令，Verilog源代码，顶层设计图。结构简单，冲突解决方式也很简单，代码量小。(A computer theory course design work, five pipelined CPU, instruction set to the code are design, the final report documents the formation of parallel division, 16-bit word length, fixed-length instructions, Verilog source code, top level design. Simple structure, conflict resolution is also very simple, a small amount of code.)

贪吃蛇程序，用verilog实现，可以运行只要修改一下相应的FPGA芯片类型和VGA接口相应的引脚(Snake program, using Verilog to achieve, you can run as long as the appropriate to modify the corresponding FPGA chip type and VGA interface to the corresponding pin)
