数字滤波器组。包含matlab程序和word说明。通过一个低通数字滤波器和多个带通数字滤波器组合成一个滤波器组(Groups of the digital filter. Contains matlab program and word description. Through the combination of a low pass digital filter, and a plurality of band-pass digital filter into a filter bank)

VHDL黄金参考手册，能让你更好的学习了解VHDL语言(VHDL gold reference manual, can make you a better learn VHDL language)

在利用Verilog在FPGA平台上输出正弦波，实现芯片为Cyclone II 484C8，有管脚分配-In the use of Verilog in the FPGA platform, the output sine wave, the realization of the chip for Cyclone II 484C8, has pin allocation

说明：  数字信号处理的FPGA实现(第4版)的配套源码，极具参考价值。(The source code of the realization of digital signal processing on FPGA (4th edition) is of great reference value.)

FPGA生成伪随机数,希望对加密的童鞋有用(FPGA generates pseudo-random numbers, we want to be useful)

system c 是在C环境下的硬件描述语言,比VHDL 等语言具有更强的抽象能力,内有system C的开发支持库和一些VC下的开发例程-system in the C environment hardware description language, than languages such as VHDL is more abstract, C within a system to support the development of the VC and some routines under development

FPGA上的VERILOG语言编程。通过查找表实现直接数字频率合成。在主控部分通过键盘选择正弦波，方波，三角波，斜波，以及四种波形的任意两种的叠加，以及四种波形的叠加；通过控制频率控制字C的大小，以控制输出波形频率，实现1Hz的微调；通过地址变换实现波形相位256级可调；通过DAC0832使波形幅值256级可调；通过FPGA内部RAM实现波形存储回放；并实现了每秒100HZ扫频。(FPGA on the verilog language programming. Lookup table through direct digital frequency synthesis. In part through the control of the keyboard to choose sine, square, triangle wave, sloping wave, and four arbitrary waveform two superposed and the stack of four waveform; by controlling the frequency control word on the size, in order to control the output waveform frequency, 1 Hz to achieve the fine-tuning; Address transform through waveform phase adjustable 256; DAC0832 so through waveform amplitude adjustable 256; FPGA through internal RAM to the waveform storage intervals; and achieve a 100 per second sweep 9999.)

利用FPGA实现频率测试,基于VHDL实现,具有良好的测试性能可直接使用-Realize the frequency of testing the use of FPGA-based VHDL realize, has a good test performance can be directly used

最近在做毕设，ldpc码的编解码实现，这个是verilog实现。(Recently completed the set up to do, ldpc code codec implementation, this is the Verilog implementation.)
