FPGA简:讲述了FPGA的基本概念、结构、发展

自己写的位同步实验程序参考，该算法需要发送和接收方的频率比较稳定时，可以很快地达到位同步，且十分稳定。位同步是通信技术的基础之一，希望对大家学习有所帮助。(The program is a reference used for bitsynchro writed by myself.When the both send s and receive s frequency are stable,the program can reach bitsynchro fastly.)

说明：  ddr2原理图设计，原厂电路图设计，很好很强大 16bit(ddr2 schematic design, the original schematic design, a very powerful 16bit)

四位拨妞开关作为输入，当输入值变化时将其转化成两位输出(The four DIP Niu switch as an input, when the input value changes, be converted into two output)

数码管显示有片选 模块 四输入，与其他模块相连即可使用-digital film of the election showed that four input modules, and other modules can be linked to the use of

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)

AMBA总线apb总线的verilog代码以及相关的中断控制。(AMBA bus apb bus verilog code and associated interrupt control.)

用VHDL语言实现QPSK调制功能和解调功能,(Using VHDL language features QPSK modulation and demodulation functions,)

Vhdl实现的鼠标协议历程，代码可读性高，适合作为案例参考。-VHDL realize the course of the mouse protocol, code readable, suitable as a reference case.

Reed-solomon decoder, encoder design note

这个是vhdl的彩灯实例程序，里面涵盖了48种的彩灯变化，通过了maxplus的验证，并且在机上实验通过-this is the Lantern example VHDL procedures inside covers 48 species of Carnival changes adopted maxplus certification, and the plane through experiments
