vedic 乘法器的 verilog 代码

用VerilogHDL写的spi 核的例子(A simple example of SPI core using Verilog HDL)

新版 小米抢购器 -源码 已经测试，代码很有用，已经抢了好几个小米3了，希望对大家有用(The new millet to snap up- source Have test, the code is useful, has robbed several millet 3, hope useful for everyone)

根据软件无线电的思想，提出了一种新颖的数字信号处理算法，对QPSK信号的相位进行数字化处理，从而实现对QPSK信号的解调.该算法允许收发两端载波存在频差，用数字锁相实现收发端载波的同步，在频偏较大的情况下，估算频偏的大小，自适应设置环路的带宽，实现较短的捕获时间和较好的信噪性能。整个设计基于XILINX公司的ISE开发平台，并用Virtex-II系列FPGA实现。用FPGA实现调制解调器具有体积小、功耗低、集成度高、可软件升级、扰干扰能力强的特点，符合未来通信技术发展的方向。(According to the idea of software radio, a novel digital signal processing algorithm, the phase of QPSK digital signal processing, enabling the demodulation of QPSK signals. This algorithm allows the sending and receiving ends of the carrier frequency difference exists, using digital phase-locked to achieve synchronization of sending and receiving end of the carrier, in the case of large frequency offset, frequency offset estimation of the size, adaptive set the loop bandwidth to achieve shorter acquisition time and better noise performance. The whole design is based on the company XILINX ISE development platform, and Virtex-II series with the FPGA. FPGA realization of a modem with a small size, low power consumption, high integration, software upgrades available, the characteristics of strong interference interference, in line with the future direction of ICT development.)

基于FPGA的16*16点阵中文LED显示，另带有几个简单的中文汉字的点阵数据。(FPGA-based 16* 16 dot matrix Chinese LED display, and the other with a few simple lattice data Chinese characters.)

OFDM中的IFFF模块实现，基于verilog实现，通过验证(OFDM module in IFFF)

ddr2存储器控制模块，大家可以拿去借鉴，其中对DDR2内部时钟刷新本人花了很久的时间。内部时钟频率请各位已经自己芯片情况而定。本人也是新手，代码中有不少地方也许欠妥，大家共同学习，谢谢。

vhdl编程语言电子书，英文的，有很多例子(VHDL programming language e-books, in English, there are many examples of)
